I've re-installed several times and I still can't get it to work.
I have a 3 computer licence.
I was able to fix an IE problem with FF on one of the computers so I started to follow the same instructions on another computer that I'm having problems with FF.
Can't do anything with the control panel once I open it.

Operating System:Windows XP Pro
Software Version:8.0
