Mouse Sensitivity in menus too high

[Hecc]

So, my house in Windhelm kept crashing whenever i tried to enter it. I read online that to fix it, you just needed to verify the game files. So I did that and NOW my sensitivity in the menus is too high and the method that i used to make it less high (going to the the SkyrimPrefs.ini and changing fMouseCursorSpeed from 1.0000 to 0.2000) has magically stopped working. if anybody has some divine knowledge that i'm missing, please share.
