you have to use submitted keygen to test if it's working.. see my tutorial, one parameter differs from hw to hw. so given serials won't work for other computers.. XxLXDxX made a nice trick there. :)

and after i checked my solution, it seems i have to write a new keygen ;) how strange i didn't implement those CPUID part in the keygen..

submitted updated tutorial & keygen. but i found a bug in keygenme. you had to use movzx eax,al after movsx eax,byte ptr[edi+esi] to make sure you generate positive numbers. suppose that the unique xor string is 0xF6, all loaded numbers are someting like FFFFFFAA and this is a negative number, so the final serial becomes ----------------------------------- cause after converting to decimal, you'll only get the minus sign, not a number.
