First of all, make sure that all the files of the game are in the same folder as the .exe, mabye you involuntarily moved something? Try running the .exe as an administrator by right-clicking on it and selecting this option. If that doesn't do the trick, reboot your PC. If it's still not working, have a look at this thread here and this post on Uranium's reddit, both contain some more advice.
