Thank you. Driver Sweeper helped fix it.

I have already tried to install the latest driver from ATI's Website.  When I do, it won't install because it says I already have the latest driver installed.  I've already tried uninstalling the old driver and reinstalling the driver ATI's website.  I still get the same error.

I have already tried.

When I go to install 9.3, it says I already have the latest driver installed.

The driver date I have is newer than the one in 9.3.

The driver I has should work because it's the official driver that comes with Windows 7 and is blessed by Microsoft.

I tried that several times.  Still the same error.

I downloaded the latest from ATI's website, but when I went to install it, it said I already had the latest:

8.56.1.15
4/24/2009

Help. I can't get by the LWJGL error.  I have Windows 7 Ultimate 64bit.

Running ATI X1600 with the latest driver
