this also doesn't always work. it did for a few friends, but not for others. i used teamviewer to turn it off for one because he didn't know how and he's still having the same problem. it works for me for the most part, but still have a random crash for really no explained reason, but it seems to be only once every few days and some are still doing it 3-4 times a day.
