When I open KSP the main menu runs fine, but when I press resume saved it doesn't just freezes for half a second (as if loading) then doing nothing. same goes for the tutorial and scenario challenges. If I press Start new game the menu shows up to pick a flag etc. however When I press start in that window it freezes all the buttons, however the music and the background keep going steadily. I've had this problem since first contract. I'm running windows 64x, I've tried both running the game in 64x and 32x, windowed mode updated my drivers uninstalled and re installed on mulitple occations. enabled and disabled my security system. Has anyone else had this problem? and how did they fix it?
