I launch the game and nothing loads and I have to use the task manager to kill the process.
How long did you wait until you killed the process? From time to time it takes a relatively long time for me to load as well on Windows 7 (seems to be caused by the OS), maybe try waiting a few minutes next time for something to happen before killing it.
You could also try to run it as an Admin, I'm not really involved with Windows 10 yet but I believe that it should prompt you for executing it once the OS wants to run it like it does in Windows Vista+, that should give you at least an indication that the game is loaded in the OS and also solve any possible access permissions (it should only write to files in the game directory anyway).
Other than that, are you referring to the latest 1.2 patch of the community patches, or the recent OpenGL port?
If its the former you might want to try the OpenGL port (link
), its still in its early stages (no options menu or multiplayer) but definitely worth a shot for the time being, especially if you just want to play the base game.
