I keep having these issues when I'm going into another game, or when I try to delete messages from my box. I get a popup to download a file. The message is as follows:

Show Game
which is a: application/octet-stream
from: http://brainking.com
Would you like to save this file?

I get this problem often. I cancel the file download, because obviously its not a downloadable file. Then I click refresh and it brings me back to the main Game List page. Then I try to click on one of my games from the list and I get the same problem. Any ideas?!
