problems after decrypting; windows won´t start

first of all, forgive me for my rusty english. The problem is this

the problem is basicly this. I downloaded the Comodo encryption program (CDE) to test for a friend of mine. At the time i had already used, and liked, the software. Then, after seeing what the CDE could do, i decided to decrypt the program, but the problem begins there. In the middle of this decryption i was forced to cancel the action due to a huge storm here in my city. In the next day i inicialize the windows XP and, as usual, it asked for the password. the only problem is that my password simply didn´t work, and i´m stuck till now trying to figure it out. please help


Which CDE version have you used?
