When I double click on the icon i get the black screen (wich is normal, it is loading) and then "kart.exe has stop working"

I tried as admin, compatibility... nothing...

Save user profile and reinstall? Maybe problem with antivirus program? Maybe installed a new track/paint that doesnt work properly?  It really sucks when it just stops working...
