Remote upgrade to R60 and then perhaps try the ‘Second Option’ from here? Getting the Player Status
I don’t think so, as far as CMS is concerned it is the same device (MAC) so it should be fine.
Although it seems to have some issues with CMS connection (or rather registration), perhaps try to remove it and add it back and see what will happen.
It is odd, we’d need to see status window and perhaps some CMS logs to know more.
