Show what values of importance are returned in the PC's internal registers after the CALL 0040CCC0 has been executed. You wrote: "Well the only register that I thought that had a lot of value was the eax register." Did you check the ECX & EDX registers as well? Within the code fragment between 0040CCC0 - 0040CDO there is this code block. :0040CCF2 xor eax, eax ;Set EAX=0 :0040CCF4 pop esi :0040CCF5 pop ebx :0040CCF6 add esp, 00000004 :0040CCF9 ret :0040CCFA sbb eax, eax :0040CCFC pop esi :0040CCFD sbb eax, FFFFFFFF ;Set EAX=FFFFFFFF :0040CD00 pop ebx :0040CD01 add esp, 00000004 :0040CD04 ret There are two values for EAX shown here for the register EAX, depending on the outcome of the serial checking.
