SQL Database Error vb_cron

Does anybody know what I have to do here:

Database error in vBulletin 3.7.0 Release Candidate 2:

Invalid SQL:

SELECT cron.*
FROM vb_cron AS cron
LEFT JOIN vb_product AS product ON (cron.product = product.productid)
WHERE cron.nextrun <= 1208357494 AND cron.active = 1
AND (product.productid IS NULL OR product.active = 1)
ORDER BY cron.nextrun
LIMIT 1;

Run a repair on your db from the admincp maintenance section and also rebuild your indexes, which is right under the repair in the same location, you need to have the mysql-schema.php file uploaded to the /install directory for the index rebuild, that file is located in the vbulletin/do_not_upload directory of your original zip from vbulletin.

Should also be located in the install folder if you didn't delete that entire folder

Buy MySQL error: 124 = Wrong index given to function. So if repairing the DB doesnt solve the issue, you may need to disable all your plugins and products and then try to run the cron again.
