Extra Customer Fields Mod seems broken

Hey everyone I installed the Module for Extra Customer Fields. First question, why is this module even available with all the warnings that are attached to it concerning Database errors, and database mess-ups? I decided to try it anyway and followed all instructions. When I go to the additional customer fields in admin I get the following error:
1054 Unknown column 'field_required' in 'field list'
in:
[ SELECT field_id, field_name, field_required, field_status, use_url, field_url FROM customers_additional]
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.
Does anyone know that this means and if it can be fixed?

Thanks a lot!!!

Hi

Did you upload all of the files associated with this mod? Check again. Is there a associated discussion forum for this link, have you tried asking there first?

Have you checked your database tables for the entries that should be there?

I to have the same problem and error after install. I have seen this same problem mentioned in a few different threads but I have yet to find a answer on why the error is there or how to fix.

I am wondering if anyone has installed this MOD without the error?
