smoke screen when i try to load a server

I got a problem with unity. it isn’t being so cooperative for me today. after I pick a server all I get is a smokeout screen with a “unity web player install now” button in the top left of the screen. I have a 7900 radeon card new from my bestest friends at the local american computer store, which I thank dearly for keeping good stock in store. I’m wondering if the problem is unity, my computer, my videocard, or something else like the website.

I’ve downloaded the free version of the whole package of unity AND restarted my computer. any help is helpful.
