This worked for me and have been going in and out the last couple of days with no problem because I followed Bun3107 info.I had to try a few times because I kept getting the Beachball but clicked continue or proceed (Sorry I don't remember which one) and game launched like it used to.Don't give up it seems to work.Also make sure you delete/move ALL WGT stuff to the trash including (Launcher and game before trying)
Good Luck
