OK, so a pretty recent version of SS, and a widget that doesn't seem to have been maintained since July last year.
It doesn't help find a solution, but it should make it easier to understand why it doesn't work out of the box.
Judging by the 404 link you posted, I'm very surprised that the fix that Fungshui posted didn't work for you. Are you sure you did a flush=1 after making the modification? Make sure you check the HTML source and check that the form action has been changed as per the mod. The fact that it is still trying to send you to that emmaus directory suggests that you haven't.
Cheers
