TOPIC: Not Receiving Info from PayPal

Hi...

I'm running version 2.5.1b, and I'm having a problem similar to the one discussed here: http://www.dthdevelopment.com/index.php?option=com_jfusion&Itemid=91&jfile=viewtopic.php&f=16&t=3726&p=3775&hilit=notification%20url#p3726

After making a PayPal transaction, the DTRegister fields are empty, a "fail" is added to the registered users database, and no confirmation Emails are sent.

(I do have IPN enabled and a return URL entered.)

The solution in the post suggests changing some code, but that code already exists within the new version.

Is anybody else having trouble...anybody know a solution?
Thank you!
