Don't know if anyone else has experienced this but whilst trying to sign up for this club tournament round this morning, I got this error message, I tried going via the normal Home Page >>>> Country Clubs >>>> Club Tournaments and also Club Forum ( via WGT.com ) Profile >>>> Club Tournaments and no matter which " Play Now " I pressed none would work.
Eventually I had to completely come out of the game, log back in and it had cleared and allowed me to enter and play.
