I really appreciate all your help, and can't thank you enough. I'm so eager to get this working and it's killing me cause I can see that you're so close to making this work. I feel bad to inform you that after trying what you have there, it unfortunately crashed. To be on the safe side, here is the signature that I'm using:
PHP Code:
\x55\x8B\xEC\x83\xE4\x2A\x81\xEC\x2A\x2A\x2A\x2A\x89\x54\x2A\x2A\x89\x4C\x2A\x2A\x56\x57
Aside from that, I used exactly what you provided, and even tried it with the printf()s commented out as well.
