Oh, hmmm, normally that means that the openGL version needed is not supported by your graphics card. It's an ATi from 2008, which is almost a double-wammy and could be quite hopeless, I'm afraid. Since the rest appears to be a proper machine, you should consider buying a more current graphics card... I mean, it's been 6 years, which is quite a long time for many sad reasons. They're really cheap nowadays, though, even the more basic cards are already superior in every way to almost anything from 4 years ago, let alone 6. So, I'd say you can do no wrong. I'd recommend an NVidia card, though, but since I solved all compatibility issues I know of, any card should do, especially ATi. Just have a look at the list and pick one, I'd imagine!

Sorry about the hassle, though!
I really wish very much that you get to run Verve soon, too, because I know just how much fun it can be and more.
