Yay!! It is resolved now. I got my code: 3420973. Now on for hunting newbies!!!
I got my referral code but now it doesn't connect to the server so I can't enter anybody else's code.
Referral code system is currently not working and may never work again. Some people sometimes report being able to get a referral code, but this is too random and not reliable. Since there is nothing we can do about this problem, I'll close this thread now.
