So i downloaded the lastest patch for BtS and installed it. The first time I went to play it after installation, it crashed and now won't start. I tried uninstalling it so I could reinstall it all over again but it won't uninstall. It brings up all the screens and even says it has removed the program, but still lists it in my add/remove program window. If I try to install over it, it brings up the uninstall wizard again, which still does not remove the program. What am I doing wrong?
