Solved....I liked this one a lot. Thanks man/m'am! Lol. Anyhow, I'm going on vacation, since it's Rodeo break for me right now, but after it, I'll put up a solution! This one deserves it!

bug is fixed now. there was no valid serial if crc32 value did not contain 8 characters. i'm very sorry that the offset numbers don't match with those of the old version but algo is the same.

thx guys for your nice solutions

from roulio's solution:
004024D7 |. 35 2037EFC6 XOR EAX,C6EF3720
004024DC |. 35 B979379E XOR EAX,9E3779B9

xoring it two times (why two times ? :)

C6EF3720 and 9E3779B9 are tean values. watch kanal crypto analyzer ;)
