Forum Site suddenly calling for phrasegroups that are missing from DB
 

I have a problem I'm hoping someone can help with. It appears it happened when I uninstalled an old vb3 mod that had been disabled in vb4. It completely crashed our site, and the database errors were all something like this:

Unknown column 'language.phrasegroup_global' in 'field list'

Which column was missing from the language table depends on what page I'm on. I've added the tables back to get the site running, but since they're blank I now have no labels for anything.

Anyone know of a way to address this short of a db backup?
