Most people want this to set up right out of the box and not to have to jump through hoops to set up PayPal. After spending a number of hours trying to get PayPal to work i debugged the errors and the software was looking for jos_mambots. Yeah ok. No great explanation of how to get Paypal going.

Wouldn't install properly on a fresh install on 1.5.3. The kicker was that I searched for a solution to the problem in their website....only to find out that I needed to upgrade to the PRO version to get the issue resolved. Not thanks.
