DirectInput problem

Hola, I have used DirectInput before with out any trouble. But i started a new game today, and i was rewriting my code and im getting errors when it comes to the DI part. They are as follows: error LNK2001: unresolved external symbol _GUID_Key error LNK2001: unresolved external symbol _GUID_SysKeyboard error LNK2001: unresolved external symbol _GUID_SysMouse error LNK2001: unresolved external symbol _GUID_XAxis error LNK2001: unresolved external symbol _GUID_YAxis error LNK2001: unresolved external symbol _GUID_ZAxis error LNK2001: unresolved external symbol _IID_IDirectInput8A fatal error LNK1120: 7 unresolved externals So i made sure the header files are inculded correctly and they are. The dinput8.lib is included in the project. The code is basicly exactly like my previous game that used DI, but with diffrent pointer names. I cant figure out what these link errors are from. Anyone have any suggestions? Thanks in advance
