Oops, I forgot to add the upgrade option to add the attach column to the table. Going to update the file to v0.3b very shortly.
You can fix this error by running the following query:
Code:
ALTER TABLE (TABLE_PREFIX)ticketreply ADD COLUMN attach SMALLINT UNSIGNED NOT NULL DEFAULT '0';
Obviously replace the entire string "(TABLE_PREFIX)" with your table prefix, or remove "(TABLE_PREFIX)" entirely if you dont have one.
