Please send in a ticket to Tech Support with the following information so we can try to figure this out for you.
It'll be helpful to us if you tell us some of your computer's information, and include any screenshots of any bugs or errors that you get.
1) What is the make and model number of your computer?
2) Please also tell us whether you are running a 32bit or 64bit version of Windows. You can find out in Windows by going here: Start > Control Panel > System & Maintenance > System. Then look under System > System Type. It will then display 32bit Operating System or 64bit Operating System. Include that info with the info we ask for below.
3) To create a dxdiag log, go to Start, click on Run, then type in dxdiag and press Enter. Click on Save All Information as a text file (on your Desktop as an example.
If you are using Vista or 7, go to the Start Menu, click on the Search menu and type dxdiag.exe.
4) Attach the dxdiag.txt that you save to your reply to us.
If you have a 64bit system, please click on the 64bit Dxdiag/DirectX button to save the correct log file.
This is important so that we can do our best to help you.
