You can contact your host and see if they have other servers that run a higher version of MySQL and if so see if they have PHP5 on it too. Read the rquirements that were stickied either last night or this morning... http://www.vbulletin.com/forum/showthread.php?325521-vBulletin-4-Minimum-System-Requirements

You're having an old version of MySQL.

Minimum required MySQL version: 4.1 (Recommended is 5.0.19)
