MarketPress - Coupons still don't work

As with many other folks, I've been spending inordinate amounts of time trying to fix all of the changes that have happened with the new MP 3.0 release. fixed several of the issues that I had previously brought up, but the coupons still aren't working.

I saw one thread that said that old coupons won't work and you need to recreate them all.

I created a new coupon today after upgrading and that coupon still does not work.

Please help!
