So I was thinking that there are lots of noobs around here that can't google and mpgh gets tons of new members everyday that don't know what to do with a hack. So before you start downloading the hack and the injector you must have all these requirements (download provided):
Direct X11
Download: DirectX 11 Technology Update - Microsoft Download Center - Download Details
Microsoft Visual C++ 2010 Redistributable Package (32 Bit)
Download: Microsoft Visual C++ 2010 Redistributable Package (x86) - Microsoft Download Center - Download Details
Microsoft Visual C++ 2010 Redistributable Package (64 Bit)
Download: Microsoft Visual C++ 2010 Redistributable Package (x64) - Microsoft Download Center - Download Details
.Net FrameWork 4.0
Download: Microsoft .NET Framework 4 (Web Installer) - Microsoft Download Center - Download Details
msvcr100.dll
msvcr100.dll free download - DLL-files.com
msvcr100d.dll
msvcr100d.dll free download - DLL-files.com
The 2 dll's above should go in your crossfire folder, and after you're done downloading these just download a hack and injector marked as [Released], never use a [Patched] or [Detected] hack or injector.
