Repair client loop

Hello,

I get this constantly:

"you have been disconnected from the game" after I've entered a game.

I have to restart the client in order to sort it out. And then sometimes it tells me that it needs to repair the client for corrupt files. Does this every 1 in 10 games perhaps, and never seems to fix the client. I end up waiting about 15 minutes by that time the game is lost and everyone is (quite rightly) furious with me.

My internet is fine, everything else works no problem. This started happening about 2 days ago.

Now I'm losing games and getting reported. Can someone explain this to me?
