I receive this error:
1054 - Unknown column 'kissmt_manufacturers_description' in 'field list' SELECT languages_id, kissmt_manufacturers_description FROM manufacturers_info WHERE manufacturers_id = 0 [TEP STOP]

upload the content of this folder: optional_extras\Admin Settings\uploads\catalog\
and run installer.php
Read this before:
