Ignore the last bit of my previous reply Dragon-Fu. Actually I restarted the machine again and checked in add / remove programs and it did dissapear so that seems to be ruled out.
Going back to the process, after uninstaling from device manager, I did restart my laptop and whe I reinstalld the driver it definately overwrite the existing files. So for some reason it didn't uninstall correctly.
Cheers,
Damon
