Luckystar5: when he tries to enter and play in a cc tourney, he says that he gets a message, stating that he has to enter a password.
This message makes no sense to me.
"Member of a CC" is a status of a player, visible by the indication in his profile, and visible in the CC's member list. There is no "access to CC" or "access to CC tourney".
It's a wild guess that the tourney might not be accessible from his platform. But I rather suspect that his member status in WGT's databases is corrupted, just like some owners who are owners of deleted CCs.
Here, a user's workaround might be
0) to check his membership in the list,
1) to change his member status, and later change it back,
2) to have him quit the CC and re-join, perhaps a day later.
