Ok, run the following queries, ignoring any errors you might get to really uninstall all database changes. Then install again, using the modified queries.php. If you are using a table_prefix, you should manually add this in front of all table names.

[sql]ALTER TABLE language DROP COLUMN phrasegroup_members_choice;
DELETE FROM phrasetype WHERE phrasetypeid = 887 AND fieldname = 'members_choice';
DROP TABLE mc_nominee;
DROP TABLE mc_pollbooth;
DROP TABLE mc_whovoted;
ALTER TABLE usergroup DROP COLUMN mcpollingbooth;
DELETE FROM setting WHERE grouptitle = 'mc_polling';
[/sql]
That should do the trick i think.
