Installation Problem with MySQL database

[kreichelt]

I am getting an error in Step 3 of the upgrade script (from 3.8.4). I am sure there's something wrong with my database, which I created by exporting my MySQL 4.0 database and then importing it into 4.1. I am using GoDaddy, and have tried a number of ways to do the export/import -- backing up the database and restoring it, exporting it and then importing it into a new database set up in 4.1... Not sure what settings I need to use in this export/import process to get this working properly. Anyone know?

Here's my error message:

Database error in vBulletin 3.8.4:

Invalid SQL:
INSERT INTO tagcontent
(tagid, contenttypeid, contentid, userid, dateline)
SELECT tagid, 2, threadid, userid, dateline
FROM tagthread;
