I was working on a cpt with a few lenses on a background object. Save as jpg, and the original cpt is now gone.
I was working off my desktop. Using X7 64bit SP3 on W7, beefy machine.It happened more than once but I can't get it to happen every time.
Only once was after saving a jpg, the other time was just saving and closing, and the file just is gone.
I went to the recent files list and it was there, but choosing it didn't work, said it was missing.
No files in the temp folder either.
What a bummer -- I lost 2 files and they took me hours.
Were those files emailed to you when you first opened them? And if so, did you open them from the email or save to your hard drive first?
