Thanks for the reply, The belkin dongle does have it's own drivers, but the software used seems to be entirely built into windows and yes, it's petty easy.
Passkey was correct, and don't know what caused the original problem...
However! The problem has magically fixed itself, lol, I have a feeling that some nice little pixies or fairies turned my computer on during the night and did something. I left the battery out of the receiver all night too, so that might have helped.
