Mouse trouble

[slafeir]

Hi I WAS able to play amnesia running windows 8.1 on my Lenovo Thinkpad X1 carbon with an i7 processor and 8gb ram as well as an intel 4400 graphics card. But ever since I uninstalled the game and reinstalled the game a few weeks later, the mouse lags and I can't click on my file to play the game let alone actually play. My drivers are up to date. I have tried replacing the SDL.dll and running compatibility for windows 7. Any help to resolve this issue would be appreciated.
