Okay, I'm back to getting the layout working again. Just found something incredibly strange.
I created a sandbox site, basically cloning the current state of our forums & DB. When I activated the vbGallery FORUMHOME MainBlock on my sandbox site, it worked just fine. However, when I did the same on my live site I got the results from my original attached image...
At first I thought this was due to me having the CMS activated on the sandbox and not on the live site but deactivating the CMS on the sandbox didn't crash the MainBlock.
Thoughts?
UPDATE: I just noticed something different between the sandbox and live site. In the admincp when I expand the vBGallery menu option in the live site, the options "modify layout" and "import / export" are showing up encased in asterisks and in the sandbox they show up just fine. Here's a screen from the live site:
