CO crashes when joining a server and SL won't update.

[Mizzuks 0]

The game was running fine until yesterday, now it just won't work. 90% of the servers have little red x's next to them, and those that don't, I can't join anyway. I'll get a message saying that the game has stopped working. Originally, I was getting messages about files missing, but I seem to have fixed this.

When I try to launch Six-Launcher and it starts to update, I get this error; http://i50.tinypic.com/333kabr.png

I was wondering if this could be to do with my router, but generally, everything has been okay so far. I wonder if it's possible to manually update Six-Launcher? If I recall, I installed ARMA2_OA_Build_94876 but I've read this may be the wrong version.

Any help with be great, I'm running out of ideas.

I can't update my six launcher either, i have to play on the current version servers.

Everytime i try to update i get 'unhandleded exception during update checksumError'
