Nice work Raz0r.

Serial Sniffing was easy as pie, will try to work on the keygen now ;)
Serial: 8Ee2589SLv8E259a

PS: Seeing the above posted serial i think that the serial number is of the format "%sv8E259a" bcoz of the following as well :-
Name:- Testing
Serial:- 8e38FUTakv8E259a

i'm not sure for string "%sv8E259a" but maybe for string "%s8E259a"

name: asjdoighau
serial: 8s47JQThkB8E259a

and if the name have len = 15 and some letters and numbers the string doesn't exist in serial.

name: 314eahr8y0755ay

I made a patch, so that the program accepts every serial you enter, you can find the patch at:
