I have the 550 and after adding an Oppo 93, I was able to update my 550 for the most basic of functions but when I went back in to assign every button to match what I wanted from the ACTIVITIES area, I get a page that reads (on the computer screen):
"Unable to display content." then the "Click 'NEXT' to continue". When 'NEXT' is clicked, the screen goes back to the activities screen. I am seriously frustrated as I've never had an issue with the 550 before. I can program it under my other 550 account (we have 3 of them) but not the main account. Any ideas?
