Gameport Error Code 12

Hi,

I'm having trouble getting my gameport to work. In
the "Device Status " box it gives the following message:

This device cannot find enough free resources that it can
use. (Code 12)

If you want to use this device, you will need to disable
one of the other devices on this system.

It also says Input/Output Range 0201 - 0201 not
available. But it doesn't seem to be conflicting with
anything. I've tried re-installing the gameport with no
success, any ideas??
