Have you tried here mate....
http://sageforum.co.uk/
I don't use Sage myself but I helped someone out with some Sage problems before and that was where I found my answers.
///Edit - I lied, looking at that place now, it cant be the one, there's no messages on there! You've posted there tho right? Of the two posts, one of them is the same problem as yours.
Do a google search for Sage user forums, I'm sure there is a few out there.
