Crash During Auto-Save?

I'm getting a LOT of crashes happening now during what seems to be an Auto-Save. No warning.. it just locks up for a moment and then POOF, gone.



I'll often end up with another .ptx along side the main one but with random letters instead, for example; "zzppHJFHpsvvPCCX".



Any ideas? I'm trying to write a track right now and can't move forward. :(
