Clear description of the problem - try and include as much information as possible, including what button and mappings you are having problems with (if applicable).:

I was messing with the left click options and turned on sticky keys (not entirely sure), but after I couldn't left click. I accidentally closed the program and now I don't know what to do. I tried shutting down my computer, but nothing worked.

Have you tired reading the FAQ? Particually the section titled:
I have changed the LEFT or RIGHT mouse button and now I can't use my computer
... How do I get my mouse buttons back to normal?

That should tell you all you need to know, and save me repeating it here!
