My wacom has gone mad!

Gah! My Wacom pad/pen has been totally mad since yesterday, i dont know what happened :S.

The main problem is that the pen just isnt working right, it seems to be delayed, it doesnt click on things properly, I have to really hit the pad for it to connect, when Im drawing it doesnt stop when I lift the pen of the pad, its like it gets stuck in drawing mode and keeps drawing as I move my pen (eventhough Im a bit above the pad).

Have you guys had this problem before?

I think I have once with my old one but this time Ive rebooted my laptop, disconnected the pad, restarted photoshop but nothing works :S.

Might I have damaged it somehow? :(

I really hate computer related issues, makes me want to pull my hair out, and kick the wacom pad on its nuts :/.

Update: Woho! I think I solved it. I found a forum on wacoms site where many people mentioned the same problem, all i had to do was take out the nib, clean the hole and put the nib back in again ^^.
