I'm getting the same problem. Worked find on mt 1.3.2 zencart. Did a fresh install of 1.3.7 for Paypal Express support, and now Recover cart sales no longer works. I check the customers I would like to inform as before and hit the send button, but rather than taking me o the second page it used to take me to displaying the customers and their products with an email sent bar at the top of the screen, the recover cart sales initial page just refreshes on itself showing all customers that abandoned their carts and all check boxes unchecked again. No email is sent at all. Have tried changing the zencart mail transport method from sendmail, to php, to smtp and still the same issue, no error message, just seems that the script fails.
Anyone any ideas? anyone got this running on 1.3.7 so I can rule out conflicts with another script?
your help would be much appreciated.

I love this mod
Thanks
John
