OpenGL Problem

In the years I've been using Torque, I've never experienced this problem. I recently replaced the hard drive in a computer, reinstalled Windows XP Pro, updated the ATI drivers, the whole 9 yards. I decided to test out the TGB trial, but am unable to load the game builder or individual games.

Creating a new rendering context...

So, it's obvious that the app failed to create a rendering context for OpenGL. Switching the preferences to run the app in D3D solves the problem, but I'm going to need OpenGL rendering capabilities. What should I check or update?

Thanks very much in advance...

*Edit* - Forgot to mention that TGE does not run either, both TGE and TGB ran on the same computer with the same specs prior to the hard drive swap, and that my video card is an ATI Radeon 9550 using the latest drivers that I downloaded from ATI's website.
