hi, (i've submitted a call for this but It would be useful if anyone has any idea as the system in live) I have upgraded from another system to amember and vbulletin to deliver my downloadable products and provide a forum for members. The payment processor is clickbank. when I do a test purchase everything works perfectly but when a live transaction happens I have to rebuild the db as new customers aren't added to the vbulletin forum. NOTE :the test purchases work ok so set up must be ok I have reinstalled the vbulletin plugin. where else should I look to find the problem ?? running 3.16
