"crashes a lot" doesn't tell anyone anything. If the game crashes a lot, i.e. it starts, then crashes later, this is problem with your computer and nothing to do with the game.
The only DRM related problem with the D2D version has since been resolve, or the game won't even work.
Make sure your that your rig meets the game's requirements. When in doubt, uninstall, re-install, install drivers, DirectX (April) etc. etc. Please READ the game's FAQ.
