Dell XT XP issue

I got a great deal off of the dell outlet. I'm really happy with the look and feel of the XT except for the fact that they forgot to send my digitizer pen with my order. Also I can't seem to get neither the multitouch to work or the buttons to work on the screen. The only button that works is the quickset, what gives?

Do I have to reinstall the drivers and if so, which ones?

 

In order to get the screen working, I'm fairly certain that you would need XP Tablet Edition.

 

sorry about not being clear on my opening post, I do have the tablet version installed but I did get the multitouch to work while messing around with quickset but I still can't get the rotate buttons to work.
