Code:

00408AC9   53               PUSH EBX
00408ACA   68 4C0A5600      PUSH TwelveSk.00560A4C                   ; ASCII "TwelveSky2"
00408ACF   FF15 1C025600    CALL DWORD PTR DS:[<&user32.FindWindowA>>; USER32.FindWindowA
00408AD5   85C0             TEST EAX,EAX
00408AD7   EB 1B            JMP SHORT TwelveSk.00408AF4
00408AD9   68 00100000      PUSH 1000
00408ADE   68 4C0A5600      PUSH TwelveSk.00560A4C                   ; ASCII "TwelveSky2"
00408AE3   68 740B5600      PUSH TwelveSk.00560B74                   ; ASCII "[Error::FindWindow()]"
00408AE8   53               PUSH EBX
00408AE9   FF15 7C025600    CALL DWORD PTR DS:[<&user32.MessageBoxA>>; USER32.MessageBoxA

No matter what I do I couldn't manage to penetrate this bad boi. The problem with this is that the Error::FindWindow() is already being jumped by default, any ideas?
