Opt, Return to Factory Settings restores BIAB to the way it worked when it shipped. It cannot do any harm.

Note: if you have set anything unusual like fonts, rows per page etc. you should make a record of those before you do the Return. Same for MIDI devices and DXi if you use that. You may be prompted to save your current configuration first, but I think that did not become a feature until version 2011, or maybe 2010.5.

Doing this is a very standard response when things in BIAB do not work as they should. All it does is erase a few configuration files that are then re-created.
