I read about your problem with AH and they seem very basically
So to help you better, i suggest to you to try this:
1. On your pc.
2. Play AH - not do anything else between 1. and 2.
If no problems, then they arise from something that normally you do before 1. and 2.
or there is some driver update to do - do not perform any update before to try my suggest if you want to try if.
Also you can email to Skuzzy as other players have suggested.
