Hi, I upgraded my aMemberPro install from the trial (3.6) to paid (3.6), now three times (twice deleting and creating new databases). In the trial I set up two products and create one user, along with the admin. Then I upload the paid files and put in the key. After that when I try and access admin, signup or login I get a page with only the words "Payment plugin error". Anyone seen this before? Am I leaving a file in the old install? I tried deleting all the trial files then installing the paid but that was a mistake. Any ideas of how to correct the situation? glenn
