After the intial embarrassment of publically annoucing that the forum registration was working last night and having it crap out again. I ran the fix again and kept it on the quiet to see if it people could register before announcing it again.
So far so good... several new users have registered since last night. But sure as shite the minute I mention it announce its working it will crap out again. Let me know if anyone hears of people having problems registering again. Fingers crossed it will stay working for the long run.
