i've seen this situation elsewhere in this forum but i'm not entirely sure how to go about fixing it as per the instructions in this thread (http://gallery.menalto.com/node/39993) as my values are considerably different.
the errors i am receiving are below, and if anyone can help it'd be much appreciated as I know this module has installed fine in the past (the same problem is recurring regardless of module version).
