I think I've managed to attach it as you asked.

The workaround for the noises on the launcher is helpful and has worked, thanks!

The mouse sensitivity slowdown happens as soon as I get into the main menu. I haven't got into a battle yet.

It's the Launcher buttons in Sanctus Reach.
Also is there a way to speed up the mouse movement? The sensitivity of my mouse seems to take a hit in the game and it drags a little but when I tab out its fine.

Is there a way to turn off the clicking noise that happens when I run my mouse over buttons in the menus?
It is actually painful for me so I haven't been able to play the game yet.
