I uninstalled the update and then M2TW started working again, only later it stopped once again and now i keep uninstalling and reinstalling both M2TW and the KB3086255 update and the game still doesn't launch. I just click and a blue circle appears next to the mouse for 2-3 seconds then....nothing. Checked the task manager and nothing pops up in the background either. I'm running Windows 7 Ultimate.
