I'm trying to get this working on a 139d cart also.
When I'm logged in and go to submit a url for approval I'm getting this error
1054 Unknown column 'REFERRER_DEFAULT_COMMISSION' in 'field list'
[insert into zen_referrers (referrer_customers_id, referrer_key, referrer_homepage, referrer_approved, referrer_banned, referrer_commission) values(2,"REFERRER_KEY_PREFIX21278635837","http://mytestsite.com", 0, 0, REFERRER_DEFAULT_COMMISSION)]
not going very well.
