I have a Prob with downloading rumble fighter i go to download the game from download.com but when 30 minutes have passed it says that the connection with the server was lost what you need to do

You can try one of the other 12 sites listed as official download sites on their page (see links). If you cannot get it to download, be sure you have the space and user rights to get the game - you may also try one of the free download clients on the internet that helps keep alive downloads (GetRight, Net Transport, etc)
