The program was updated while the description wasn't, the new executable doesn't crash when you click on check. :)

Well, yeah, that's the point, it crashes the program if you don't enter a valid serial :\

@lqtnqstk: Really? thanks xD
It's not really difficult, if you need a hint PM me..

The crackme is so strange you know?
There is a lot of waste code in that.
such as the string "wduf{hy", and "sasasas" is just used when testing the username is 7 chars or not.
the app also retrive the volumn serial but not use it.

Debuging waste code really spend me plenty of time XD.

Thank's Sinok, this Crackme was quite tricky. Might be to hard for stage 1 maybe, but I (the n00b) finally found a solution, so maybe it's right at lvl 1.
Good to hear, that those strage strings were just fake ;-)

Next time I'll post the source as well.

PS: Did you know, that when you use exactly 12 characters for the username, the serial will be exactly the same ?

Didn't know I had the same bug with 12 characters >.<
