Help me please!

Hi bro!
I changed the base Eagl3, when I open warrock, the menu you see very well and functions well, but if nothing happens within the active game.
I thought it was a problem of detours?
xDetour.h :

void *DetourCreate (BYTE *src, const BYTE *dst, const int len)
{
BYTE *jmp = (BYTE*)malloc(len+5);
DWORD dwback;
VirtualProtect(src, len, PAGE_READWRITE, &dwback);
memcpy(jmp, src, len); jmp += len;
jmp[0] = 0xE9;
*(DWORD*)(jmp+1) = (DWORD)(src+len - jmp) - 5;
src[0] = 0xE9;
*(DWORD*)(src+1) = (DWORD)(dst - src) - 5;
VirtualProtect(src, len, dwback, &dwback);
return (jmp-len);
}

sorry if the question is trivial, but the beginning!
Thanks in advance for any replies!
