At the risk of beating this dead horse, I'd have to agree the upgrade prompt caught me twice (actually 3 times!) today I figured I'd go ahead and upgrade, ugh, problems... which I posted earlier regarding address books. I ended up grepping the XML files and recreating all my entries, hopefully I won't encounter any more issues or ones that require quite the effort that was.
Uninstalling v7 and re-installing v6 on previous "click to update" whoops... wasn't a big deal for me but your download page doesn't provide a link to v6, you would have to come here to get that info. Thankfully I keep older installers for several programs (RU is one of them)
I do like this program but there are oddities that are frustrating and expose some programming issues within the UI and core software, having been on both sides of this coin (programmer and user) I am very familiar with the difficulties with anticipating the infinite number of variables you have to deal with.
I tend to deal with the problem directly and only post here to bring to light issues I've encountered, I don't really expect solutions to the issues because I've already been down that road enough times to know the drill (uninstall/reinstall, turn off FW, use run only agent, etc etc)
