did you check your temp directory?
It's located under C:\Users\YourUserName\AppData\Local\Temp
The only TMP file I eventually found was also 0 kb. Thanks for the filepath to the temp directory though.
LAN Admin did manage to restore a partial backup, but I still lost about 2 hours worth of work. Now I am saving the form in 3 different locations every time I complete a section.
This has happened twice to me in the last 2 days - on the same form (the one I had to start over on!), at the same place (bottom of the first page). Any thoughts on why this is happening?
I never found out why this happened. I now save each form I am working on in LiveCycle in two different locations, one on the server and one local. It's a bit of a nuisance to Save then Save As, but I use shortcuts to make it a bit easier. And it's not nearly as frustrating as losing hours worth of work.
It would be nice to know why such a disastrous crash can happen, but that seems like a developer-level issue to me. Way above my pay grade.
