Win 7 64b. I doesn't clear if I wait for it to respond. xplorer2 lite doesn't appear in Task Mgr in Apps or Processes. The computer has been cleaned of excess files and garbage. What can I try next? i don't know if this is a clue, but the preview button is active but i can't change anything cuz the windows blue orb is turning and can't do anything but close out the program.
