Blender 64bit crashing when graphics tablet connected

I am having trouble with Blender 64 bit and a graphics tablet. It seems that when the tablet is connected, Blender simply crashes on startup.
I think this maybe be something to do with the driver because Blender used to work fine before I installed it.

My tablet is a uc-logic SuperPen wp5540u. Its hard enough to find a driver that works as this thing is pretty old now (the driver currently installed is for a Genius WizardPen or something which works perfectly in Photoshop) so I hope theres a way to make this work without having to remove the driver permanently!

Blender 32 bit actually works fine with the tablet connected and pressure sensitivity works very well too. So why would Blender 64 bit not work?

Hope someone can help.
