My tablet pen on the pen-side does not work. I've tried un-installing and re-installing the drivers and restarting my computer multiple times but there has been no change.

I've tried the tablet on my brother's computer and I get the exact same results.

So what's cheaper? Getting a replacement pen or taking it to be repaired somewhere?

(And should I get my pen replaced, or is it the tablet which is causing the problem?)

Thanks in advance.
