I'm fine with boutcheetah on my pc and my bro wanted so I installed on his pc. I read through several forum posts and updated my graphics driver (it worked after that). But then when i selected the high server and the top channel thing my windows firewall pop-up came up, i allowed boutcheetah but then boutcheetah stopped responding and i closed the program. I restarted it and now it doesn't work again :/ I've re-installed, repaired the client and tried in various compatability modes. (I also downloaded .NET 4, directX and MS C++ under the downloads page). I freshly installed Win7 so there shouldn't be any problems with viruses or anything.

I've attached a screenshot and copied/pasted the error message below.
