Graphic tablets and Touchscreen problems

I have a Trust flex ultra thin graphics tablet and a HP Pavillion 15 which has a touchscreen with 10 , touch points. How ever whilst I managed to get the graphics tablet to work with Windows 7, the moment I upgraded the laptop to windows 8, the graphics tablet does not function at all.
The laptop has a Trust Tablet control panel feature that has controls as if the tablet was a mouse but even then, no matter how many times I connect and reconnect the tablet, the laptop does not recognise the tablet.
I have Googled the subject but annoyingly, all I get are sales links to the same tablet but no solution. Can anyone help?
