Thanks, folks.
Yeah I don't think the new OSCAM file has been installed properly as I don't see a third additional OSCAM available (more info below)
When I go into soft cam manager I see two OSCAM options (which I did yesterday) also. OSCAM-emu and OSCAM-latest. I believe latest was ticked yesterday and channels were clearing. When I tried to stop that today and restart, channels haven't come back since.
When I hit the green button on either, (which was the same error) yesterday it says no config files found please setup OSCAM first / var tuxbox etc (this was the same as yesterday) though channels were clearing. Gut feel is the OSCAM version is wrong and the latest IPK hasn't installed properly ill try the usb method of getting it on the box
