1) Does this happen every time?
2) Are you trying to join H2H or ONLINE?
2a) If it happens in the H2H, make sure that you don't join a server that is full. Example if I hosted game in the H2H: This is what you may see.
ARENA Player Count
Pokie 3 / 8
The 3 (1st number) is how many players in my game, the 8 (2nd number) is how many players my game will allow).
Note! Sometime you may try joining a server that has 1 spot open and when you try to join you can get that message. I have had that happen to me because someone was doing the same thing and beat me to it.
2b) If it happens to you ONLINE,
1) are you a member?
2) has your 2 weeks free time elapsed?
