This is a problem in vbulletin ibproarcade and new games having long names..
If you look at the error code from above..
Error #011 -> gid=10714|ui[a_sess_gid]=10714|g[gid]=10714|vs[mid]=31|vs[gname]=SummerWarsHiddenObjectsAS3v2cl|gamename=SummerWarsHiddenObjectsAS3v2class
Look at the gname and gamename...They have to match or the system thinks your cheating..
The gname is shorter..
To fix this you have to up the limit of the games_session and games_list data base, gname, varchar()..
alter table `games_session` modify `gname` varchar(60) NOT NULL;
alter table `games_list` modify `gname` varchar(60) NOT NULL;
