@ikuro just reimport the XML file and reupload all files..
@whitevans, run the following queries, it will delete everything and start over.
PHP Code:
ALTER TABLE post DROP COLUMN `icash`
ALTER TABLE forum DROP COLUMN `icash_prethread`
ALTER TABLE forum DROP COLUMN `icash_perreply`
ALTER TABLE forum DROP COLUMN `icash_perchar`
ALTER TABLE user DROP COLUMN `money`
THEN install the XML, (redownload though)
