Sorry - I don't remember if I already mentioned this:
Companion Engines won't work for me anymore. I didn't use it for about 9 months so I expected it to update which it did, then it didn't work at all, except to say updating (again) then go invisible once the update was finished.
I tried uninstalling it then reinstalling it - same. Yes I've downloaded the latest installer.
