<p>Hi!</p><p>I've hit some problems when upgrading popfile to 1.1.1. and don't really know where to begin looking to sort them out and since all I really want to do is upgrade Mercury... do I need to upgrade popfile to the latest version in order to run the latest version of Mercury or would the latest version of Mercury work with popfile 0.21.1?</p><p>The issue I'm having with the popfile upgrade is that popfile crashes whenever I open the "security" or "configuration" tabs in the UI (in case anyone here has seen that issue before).</p><p>EDIT:</p><p>In case anyone else runs into this... the problem was that the old popfiled merc.pm module was still in the proxy directory of popfile. I removed the file (...\popfile\proxy\merc.pm) and could once again access all the tabs in the GUI. Upgrading to the latest version of popfiled was then easy. </p>
