This is my first crackme i have ever tried, and i found the password in plain text using simple assembly explorer. Not sure if that was the way to crack it.

if solve the algo, not must be difficult do a keygen in any languaje there you can do but only are registred for that time, about the serial correct, there exist only 1 online valid, and many offline

Wow, pretty hard. Reversing it and encrypting it again and again.... sure doesn't help. Maybe i'm just a noob but I give it a 6/10 in difficulty, taking to account that i can see your whole encrypting process and I know .net really good.

Cracked.. but i didnt figure out the algorithm.. Actually i only tried for 40 minutes and decided to crack like i usually do..

Hint: Small exploit on the second message box ;)
Hint2: this Hint has nothing to do with keygens. If you are planning to keygen it.. i don't have a good advice.

1 - serial must not be empty
2 - serial must be 19 character
3 - serial must be seperated with ( - ) at positions 4,9,14
4 - positions ( 5, 10 ) must equals to F
5 - positions ( 0 , 18 ) must be numbers
6 - sum of position ( 0 , 18 ) must equals 10

valid serial :

Yeah that is quite easy but server isn't working anymore -_-
