Having the same problem as this guy. Wife's PSN account can play Buzz online but my account can't play Buzz online (same ps3). I can play all other online games with my account with no problem.
Any help Moderators?
Yo, Sony Moderators! Can we get some kind of a response here? Like, "Thank you, we're looking into this." "We are working with the Buzz! team to find out the cause of this." or "We value your money but don't really care for you or your problems with our software/PSN network."
