where the hell did you find loopd in that crackme? :o There's no instruction like that in asm even. Unless you mean LOOP itself?

This instruction decrements the cx register and then branches to the target location if the cx register does not contain zero.

; “loop lbl” becomes:
dec cx
jne lbl

I stand corrected, LOOPD is exactly the same instruction as LOOP (decrements entire ecx rather than just cx)

Need some more work to find a good serial. Right now I don't see how to find one. I have to digg a little deeper.

yeah, finding ID is quite easy.... (username: hasherezade, ID: 1250705268), but it's nothing in comparision to the serial hashing procedure. i wonder, should we brutforce it?

No, you don't have to brute force it. just understand the code.
