Not a lot of people look at the help board. Also, I had the num. lock on, that fixed my building problem, but my volume buttons still work like c and b keys for some reason :/
For someone looking to help someone, they won't check General Discussion.
Usually when I get on the forums the first place I look at is the help section to see if I can help anyone out.
Anyway, seems to me like the it might be an issue with your keyboard.
Make sure if your keyboard has come with special software that it is installed.
Also be sure that Num Lock is on, and any other key modifiers are off.
