I had the G99 error code 8-7-2015 after a small patch. Three computer geniuses from my outfit worked together on it for 7 hours (they should all get medals) and couldn't figure it out. Turns out THE PROBLEM WAS MY WIFI ROUTER. Apparently something had gone wonky with the patch and screwed with the router somehow. Try tethering to your phone or connecting to a different internet source. It's worth a shot, and it doesn't require 10 years of computer science in college to do.

Hope this helps some of you!

Best of luck.
