The only thing I can think of is if you didn't install the driver from the cd first, go here - http://www.wacom.com/en/support/drivers choose your tablet, and your operating system, download the latest software, install & follow the instructions. With my tablet I had to put in the cd first and it asked me to plug in the tablet a little later through install.
Hopefully that helps.
