Poser 11 crashed...and when I tried to start it up again, it was in trial mode. I had to put in my serial number again. It started, but all my preferences were nuked.

Weirdly, it seems to have corrupted all the Poser files I'd worked on recently. Not just the one I was in when it crashed, but several others I'd worked on that day. A file from last week was fine. (Does Poser keep files in memory or something, even when you close them?)

The files appear to be the size they should be. But when I try to open them, I get an error message saying, "The file being read is not a valid Poser file." I get the same message if I try to open them in Poser 12.

Is there any way to fix this? I haven't poked around in the .PZ3 yet; I'm not even sure what to look for.
