Just a randomly generated, 10 character password that only uses 0-9, A-F...

You should be able to do this easily.

to figure out password, place bpm @;

004543AB |. 8B15 007C4500 MOV EDX,DWORD PTR DS:[457C00]


If your into figuring out how it was calculated goto;

00454364 which is "FormLoad" or "FormShow", inside first function is a 'QueryPerformanceCounter' CALL. Followed by routine calls, that mess with this value.

No point in me pasting my password, as it is and will be difference from yours.
