Help Me Computer Geeks!! (Details Inside, Please Help)?

I am very technically savvy but today I am just having major problems. I take online courses and part of today's enrichment activity is to play a game online and answer a few questions. a href="http://www.bbc.co.uk/science/cavemen/challenge/index.html" rel="nofollow"http://www.bbc.co.uk/science/cavemen/cha…/a is the link. When I go to the link I go to the little picture and push open, then I get the message: [an error occurred while processing this directive] Does anyone have any ideas? If you don't, could you please check the link and tell me if you get the same message. I have tried this on two different computers on my network. It happens in both internet explorer and firefox. I have Adobe Flashplayer 10.0.22.87. I just don't know what to do!!! Any help is appreciated. (One computer is running vista, the other is running xp)
