Re: Recover dwg 'file not valid'
It was posited earlier to look in your Temp file for SV$ files and see if these are more recent.
Search SV$ if the Temp folder is not readily apparent.
Have you tried to just use Recover from the big red A menu?
And what size is the file that you are trying to open? It may not be viable.
Temp File location can be found under OPTIONS; Files tab:

I have had this happen to me several times. The recovery file generated can’t be opened. I found that at that point there was little that I could do. BAK files are always older than the DWG file they are backing up. Since it seems there is no SV$ I think that all you can do is open the DWG file and redo your work. This happens regardless of the release of software. It's unfortunate. To help remedy situations like this I tend to save (by pressing CTRL+S) every few minutes. It's a habit that I have gotten into and has saved me several times. Also check your auto save settings. Bump up the save time interval. Make it ten or maybe even five minutes. The problem with that though is that it may interrupt your work to execute the save. I find it annoying when it does which is why I manually save the files myself so often.
I know this doesn't help your current situation and I wish I could help there. I wanted to share my experiences with you demonstrating how I deal with this constant issue.
