SQL Database Error vb_cron

[abroad]

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;
