[RedTrinity]

Hi, just installed this for the first time, followed the instructions, getting this SQL error when I activate the block, which messes up the forum:

Database error in vBulletin 4.2.2:

Invalid SQL:

SELECT
user.username, user.usergroupid, user.lastvisit, user.usertitle,
session.userid, session.inforum, session.lastactivity,
IF(displaygroupid=0, user.usergroupid, displaygroupid) AS displaygroupid, infractiongroupid

FROM redtrin_session AS session
LEFT JOIN redtrin_user AS user ON(user.userid = session.userid)
WHERE session.lastactivity > 1390984366 AND user.usergroupid IN ()
ORDER BY username ASC;

MySQL Error : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')
ORDER BY username ASC' at line 8

I've double checked everything, can't seem to work out where the problem is. Help!
