I am running LDD 2009. Am getting error messages that "command not allowed because drawing contains objects from a newer version of this application", which has affected several commands. The drawings have indeed been drawn in ldd 2009. Any help please?
Have they ever been shared with someone who might have plain ACAD in 2010,11,12? If they were saved in any of those versions they may be toast.
The dwg have not been used by newer versions. I created the drawings on 09. I have done a repair to no avail. Any other ideas would be greatly appreciated.
Are all the servie packs for 09 installed? Have you tried to reinstall LDC? (If you do, remember to include the SP's)
