As the topic states. Had a logitech G9 installed and was playing through the game just fine - was 3/4's through. Bought a new Razer Mamba mouse, uninstalled software for the Logitech mouse, installed Mamba software and mouse and now the game loads into the last campaign save, then screen freezes and locks up and have to Ctrl Alt Del to kill the process.

New mouse works flawless in every other game I play, CoD:BO, BC2, Crysis 2.

Trying a re-install but doubtful it will fix anything.

Update: Turning off the Mamba/Razer control software in the taskbar stopped the freezes and crashes. Wierd, but glad I can play the game again.

I own a Mamba as well and the mouse doesn't work well in the menus what about you?

Razor mice are nothing but a major PIA. Have one, and it is back in the box--they really a major pain. Went back to logitech and everything in every game is sweet again

Real constructive post.

They are not a major pain maybe if the gaming industry handled the dpi on mice correctly like source engine games do we wouldn't be having this problem Razer mice are great never had any issues with anything else besides this piece of [censored] game. This is literally the worst game launch in recent memory

No problems on my end. I use Logitec and Nividia. No problems.
