Reinstall didnt help either.  Still can't open several files I was working with, even though I saved them before the crash.
Could it be the file size?  One file I have that opens no problem is 59 MB (4 Daz figures and some props), but one that won't open is 63 MB (only 2 Daz figures and some props.) 
I submitted a bug report to Daz also.
Harrumph!!
