4.0.3 Server Errors

[Digital Jedi]

The most recent vB version I have access to is 4.0.3. I've had my dev board running this since it was first released. I recently needed to move my dev board to a different directory, so I went ahead and just removed it from the old one, created a new database and db username and installed it fresh in the new directory. Now I'm running into server errors I wasn't running into before. What's New turns up a blank 500 Internal Server Error. But the creation of new threads or forums turns up something like this.

Invalid SQL:
INSERT INTO vb_searchgroup (username, contenttypeid, groupid, userid, dateline)
			VALUES ( '', 3, 2, 0, 1382747352 )
			ON DUPLICATE KEY UPDATE  username = VALUES(username), contenttypeid = VALUES(contenttypeid), groupid = VALUES(groupid), userid = VALUES(userid), dateline = VALUES(dateline);

MySQL Error   : Got error -1 from storage engine
Error Number  : 1030

So far new posts, vBulletin Options and saving styles seems to work. (Though, I thought edited stylevars turned red in the Admin CP)

Add to that, I just noticed I have no Admin CP help. Reuploaded the files and everything.
