Installed connect! V4.1 on a client win 7 machine which had V3 (V3 worked fine , uninstalled V3 before installing V4).
The connect! client application found all my channels (produced a grid with all my channels).
Ran MC setup and it finds no channels. Tried this a dozen times, no dice.
Tried just scanning for channels, nothing.
Tried syncing dvblink add in, nothing.
Re-installing the OS is not an option.
