So I've been noticing that when I try sending game invites to friends on games like killzone, umvc3, or resident evil revelations to play online that it will result in an error message that says "could not send the message" or it will say "The database is corrupt. Restart this system". My friends and I are both on the latest henkaku (not the new beta version) and are using the exact same dumps of these games and its the same message for all the games. We tried restarting and rebuilding our databases over 5 times and we still have the same issues. The weird thing is that initially we are able to send/receive invites to play together but after a while it just seemed to stop working altogether. We/I can still play online with random people but unable to send invites to each other to play online. Ad-Hoc mode works fine though. It seems/feels like a system issue. Anyone else experiencing this issue?
