I tried to do some conversion of my massive GS2.5 files, but everytime I try, I get some sort of irregular file error, which, of course, is obscurred by the converting screen- and it just sits there. I left it for 3 days, with no luck. Also tried single programs, different ones, etc.
I had this problem on some corrupted GS2.5 files. I re-loaded them from the original library CDs, and they converted fine. GS3 and GS2.5 seemed to tolerate the corrputed files, but GS3 wouldn't convert them, until I replaced them with clean copies.
