Modding Rule 1:

IF you install something and the game suddenly stops working ..

TAKE IT OUT AGAIN

You will probably be able to play again.

Now...when you add something, it is vital that you read the instructions carefully, install things exactly as described, and don't skip any steps, no matter how silly or irrelevant they may sound.

Also...when posting for help...or hhhhhhheeeeeeeeellllllpppppppppppppppppp, it is always a VERY good idea to say exactly what you did. What did you install, what changes did you make, and so on. There is very little chance that anyone will be able to tell you how to fix things if we have no idea what you did.
