nevermind

I just installed the dev version, which resulted in some SQL errors at the update and all the expiration dates for my nodes were deleted. At a cron run I get the following error:

user warning: Unknown column 'a.expiremode' in 'where clause' query: SELECT a.nid, a.expire, b.title, b.changed, c.name, c.mail FROM node_expire a LEFT JOIN node b ON a.nid = b.nid LEFT JOIN users c ON b.uid = c.uid WHERE a.expire <= 1261229355 AND a.expiremode != 0 AND a.lastnotify <= 1260970155 AND b.status = 1 ORDER BY c.name ASC, b.title ASC in /home/greencan/public_html/nassellajobs.com/sites/all/modules/node_expire/node_expire.cron.inc on line 31.
