From the behaviour your reporting my guess is that the drivers you installed are corrupted.
uninstall the drivers using Device Manager THEN use the driver provided on the install CD. If no install CD was included then 1st disable your antivirus or anti-whatever software then have Windows do the driver update for you.
Normally when you plugin the USB adapter for the 1st time Windows will search its approved hardware platform database for the certified drives and install those automatically --- you do not need to go to the Belkin site to download anything.--
