Mouse, ET, Vista issues..

Basically, recently ET has stopped recognizing my mouse 3,4 and 5 buttons, i havn't changed anything so i dont see why this has happened. It just stopped working one day. I've tried updating drivers, and that hasnt worked. The mouse im using is a Razer Diamondback, and im running vista home basic. I've googled around, but not found any real solutions, alot of WoW players have had the problem, but they've fixed it by closing xfire, which i dont use. - The buttons work fine outside of ET.

Second problem, since ive started using etmin again, im getting crashes at the end of every map, im guessing this is because its not running et.exe as admin, anyway i can get etmin to do that?!

The two problems are unrelated - i.e The buttons still won't work if ET is run in admin mode..

Thanks
