IGZ Friends Error

SYMPTOMS
When you log in, or all of a sudden, you get an IGZ Friends: Network Connection Error 10000001

CAUSE
At the moment, only 1000 people can use the IGZ Friends. If 1000 players are already using IGZ Friends, then you can't use it, and you'll get this error.

INFORMATION
All you can do is clicking again on the button "Friends" (next to the button "Lobby Launcher") and hope someone else just left that had IGZ Friends on, so you can take his/her spot.
