Edit Subscription expiration date has SQL error

Upon editing user expiration date the following error appears:

ERROR: Unable to execute query

UPDATE subscriber SET pack_id=, expired_time='2009-11-30 00:00:00' WHERE UID='2'
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' expired_time='2009-11-30 00:00:00' WHERE UID='2'' at line 1

ALSO- have deleted several existing packages, yet on the selection box for editing this section- all the default packages are there- not the ones i edited or added- oh and yet another i've never seen....

This bug is fixed, bug fix will available shortly.
