Database error in vBulletin 3.0.7:

[IWLSR5]

I posted this same question under vbulletin.com, but they directed me to vbulletin.org because the error is related to a hack? The problem is, I have no idea what hack is causing the error.

Can anyone help me with this error? We're getting automated emails with this error, and can't figure out why? Any help would be much appreciated.

The hacks we installed are:
1. Links Database version 1.60
2. vbChat
3. Aambience (Skin)
4. Admin Alert (Alerts us with the login info of people trying to access admin)

I believe Links "Database version 1.60" was the last hack installed, but everything has been running fine for nearly 2 weeks. Now all of the sudden we're getting this error.
