Plutonium

Client closes when trying to connect to a specific sniper server, which I have played on before.

This is all I get and a sound of clicking something in the menu, over and over again. I was playing on the server yesterday but doesnt work anymore. I've tried reinstalling pluto and mw3, repairing files, switching to another account.

what is IW5MVM ?

So basically my sensitivity is going all over the place and the game feels like its stuttering when i move my mouse to the point its unplayable. Random 180s etc. Have set the priority in task manager to normal and polling rate cant go under 500hz.
