Sorry to hear that that happened! I had to reinstall my windows a couple of months ago as well due to some big problems, mainly because i switched some hardware...Woke up this morning and my wireless card would not work. while troubleshooting that there were a bunch of other errors occuring with my PC. I wound up doing a PC reset and now have to re-install everything. I'll try downloading and running the game again and see if I have better luck after a full windows reinstall.
Good luck! =)
