UNiQUE made a fix for 5.2 back in 12/07 when it was originally released.

I tested UNiQUE fix but when i load the idb "pirated" Ida says "Database corrupt". If you apply my patch you will able to open the database. In other words my patch really works. You dont believe??? Ok, try youself!

So your patch did indeed let me open that .idb whereas the UNiQUE fix wouldn't. If the ida64.wll suffers from the same fault, would you be so kind as to make a patch for it as well?

you can see comparison after MD5Final call - patch it

in ida32.wll method is similar
