The updated module works just fine. Thanks!

Another question :

I read this in the docs regarding custom coupons :

Coupon dates – Please ignore these fields, as Mailbeez will override these settings in configuring the expiration date for your campaign

So, let's say I want to send customers that have not purchased in 90 days a personalized free shipping coupon valid for 14 days from the date they receive the e-mail. Where would I set this expiration date?

I've read about how to create the coupons (http://www.mailbeez.com/documentatio...pon-campaigns/) and I'm pretty sure I've done that part right :)
