Mouse not moving Ingame?

[Kiimse]

Hello fellow Player's,

this morning i started BnS as usuall, to get my Challenge done.Everything was fine when I accessed the Client, pressed start Game. But when I got into the Game itself (does that make sense?) my Mouse stopped moving... Cant type my 6 Digit Keycode. Nothing. I have to press my Windows-Key to get out of Fullscreen and then move my curser to the point i want to click, click it, then go out of Fullscreen again and that all over. I tried it until got ingame, but nothing changed :(
Played Yesterday and since then nothing changed software like nor Hardware like...
Help me out >o<
