Hi Dummergold,
I'm not very good. But I understand your problem. Have you try to unistall the soft ? First things to do !
And check your setting. so press S => then go to the 8th (show high head (3D)) or something like that and the wheel appears normaly. You can look transparency setting at the bottom of the page.
Hope it helps you. I'm not good enought to help..
friendly,
Flo
