I upgraded my J1.5 to the latest NPPD version 1.92. It works fine. I used Jupgrade to update my Joomla to 2.5 and now I have no NPPD. I installed the 2.5 version of NPPD and it wipes all my data. I have checked the forum and could not see a thread on this. I figure I am not the first person to upgrade though. Any help would be great.
