"Converting" back to SMF - broken .sql

[tralce]

So I used to have a forum a year or two ago running on SMF. Before shutting it down I backed up the database from the admin panel. Unfortunately, I did not tick the "table structure" box and as such a number of columns are missing. Is there any way to get around this easily, or do I really have to manually edit all 34000 some lines of sql?

What version of SMF was it?

The forum was completely inactive since then, or converted to another forum board?
