Error: Can't create GL render context

I'm on a virtual version of Windows Vista on my mac. SL was downloaded on the mac successfuly months ago. However, after downloading SL to the Windows Vista virtual the Icon does appear on my Windows desktop. I then click the Icon to get in and this is the error I receive, after it appears to be opening: "Can't create GL render context" Can anyone assist me. Thank you.

I'm having the same problem. I'm on XP and I get that same error. No luck trying to fix it so far. If you or someone else figures it out, I'd love to know what you did!
