I had problems with my computer being very slow and crashing too, I realized when I was signed into Autodesk 360 it was using all my computers virtual memory, no matter how much space I allotted to it. I've stopped signing in ... that seems to have solved the problem.
I had the same problem too when I tried attaching my x-refs???
The thing is, some of my drawing with x-refs attached, they seem to reload fine but others are not. And the ones that show the attached x-refs but need to be reloaded, I can't even reload the x-refs, It doesn't work???
I had no problem with 2012LT until I got upgraded to 2013LT this week.
Thanks for your help - Nelson
We're experiencing the same issue with 2013LT and here is the work around for it
"Some of you may be experiencing some difficulties with xref in AutoCAD LT2013
Xref’s are not loading properly and the reference file status is “unresolved”
For parent drawings which have multiple xrefs, the RECOVERALL command will process the parent and all xref drawing files. Please note that the RECOVER and RECOVERALL commands should be run on drawing files which are closed.
Keep in mind that when you perform the “RECOVERALL” it will convert any recovered drawing files to the native version of DWG for the version of AutoCAD used to perform the command, another words you do this in AutoCAD LT 2013 it will save it as a 2013 version and anyone with 2012 will not be able to open the drawing. If you need compatibility with 2010-2012 (or earlier) AutoCAD products, it may be best to do the RECOVERALL with a version of AutoCAD from that release cycle, or you can do the following:
the DWG Convert tool is available on the Save As fly out from the Application menu (or DWGCONVERT at the Command line). That tool can be used to batch convert drawing files from one DWG format to another. So, if RECOVERALL in AutoCAD 2013 converts all files to the 2013 DWG format, DWG Convert could subsequently be used to convert them back to the 2010 DWG format (or 2007, 2004, etc.) in one fell swoop. I should also point out that eTransmit can be configured to convert drawing files to whatever version you need, too."
Not sure if this will help, but my xrefs were coming up as invalid when I tried to insert them into a drawing. I went File/Drawing Utilities/Recover, selected the file I needed, and let it recover the drawing. A window would come up saying 1 error found, 1 error fixed. Close and save the xref. Now I was able to load that xref successfully into my drawing.
Hope this was a help to someone out there.
We are also getting "invalid" xrefs in 4 of our licences. This is completely unacceptable as it is adversely affecting our workflow. There appears to be no pattern to which drawing files, how 'deep' they are within the file naming protocol or what version they have been saved in/as, to allow us to identify what drawing files may be an issue and what one might not. We tracked down an "Audit Fix" that when a drawing with an invalid xref occurs you undertake an audit, with fixes activated, on the file whereby it finds and fixes 1 (one) error and then the xref is reloadable and appears to work fine...if there is only one xref in the drawing. If a drawing has more than one xref, the audit process still only picks up one error and then will only enable one xref to be visible. We then need to effectively 'rebuild' the drawing to enable all xref's to be seen again. Almost ready to delete 2013 from our system...very frustrating! Some files are taking up to an hour to re-setup to enable us to work on our drawing files that we have never had any issues with in previous versions, 2012, 2011, 2010, etc...
I was having invalid Xerfs also in AutoCAD 2013. I took out the annotative text in the xref and then it xrefed OK. As future trouble shooting I need to see what was wrong with that annotative text. I have had annotative text in many xrefs. Why this certain text did not allow xrefing I don't know.
Maybe someone should inform Autodesk of the importance of XREFS so that they will write a patch to get this issue resolved. I am finding that I have to "RECOVER" the same XREF on the same drawing everytime the drawing is opened and edited. The XREF hasnt changed, just the file it is attached to. BETA testing may be useful too Autodesk??
If you are having to recover each time have you unloaded all the XREF's from everything, opened each drawing to confirm that these are okay, and then reloaded the XREF's?
After having done so does the problem still persist?
This would confirm a LT 2013 issue and not a drawing issue.
At that point it may be worth filling out a bug report.
