ash, I was talking about the exact same plugin you were. Read the very first post on the plugin page.

This plugin is only meant as a simple way to fix roles for users doing reverse integration of bbPress with WordPress without having to resort to using phpMyAdmin but it may have other uses if a primary admin role gets corrupted or wiped out for some reason.

So really, unless your admin role is being wiped out somehow, this shouldn’t be needed in the situation you describe.
