Well, i'm pretty sure you have to go
[php]typedef int (__cdecl* RunConsoleCommand_t)(char* cmd);
RunConsoleCommand_t pRunConsoleCommand = (RunConsoleCommand_t)0x00485E10;
pRunConsoleCommand("any command you want");[/php]
This is what you should be putting in everytime, i'm pretty sure.
I haven't tested this out yet.
