During installation of foxfire upgrade the install was 95% complete and then no activity< so I waited 15minutes for things to continue. There was no change so i decided it needed to be redone however my computer was completely frozen. That has never happened before. After final deserate measures(pulling the plug) and restart I tried to uninstall foxfire so I could install from scratch however my computer is unable to uninstll and when I try to insall foxfire from scratch at one point it says foxfire must be turned off< well I'm reluctantly using explorer and foxfire has not been on in 2 weeks. What can I do to get foxfire back?
