Tablet Pc Eraser Pen

Pen pressure wont work on photoshop CS3?

i just got a Fujitsu lifebook T2010 tablet PC but when i go on photoshop CS3 and select pen pressure it wont work, also when i turn the pen over/upside down the eraser doesnt work, it still draws with the brush.
however, when im drawing on msn, the pen pressure does work and when i turn the pen around, the eraser works too, so there shouldn’t be anything wrong with the pen or laptop.
please help! =)
its not a tablet but a tabelet pc. its like a laptop with a pen, and the screens a touchscreen with bluetooth so you can draw straight onto the computer without an extra tablet

It sounds like the drivers might not be installed right. Try and putting the disk in that came with the tablet and reinstall the drivers that might solve your problem.

Good luck
