Ok, I've upgraded the forums to 1.1.16. I was up anyway, and I was the only one on the forum.
I then proceeded to upgrade to 2.0.2 which completely broke everything! (Of course.)
So, the forums are current on security patches now, I've added Video Support and Spam registration has been installed and appears to be working.
I'll fix the Avatars after some sleep!
An original copy of the forums has been saved as well. Please let me know if you notice anything else amiss.
