If I try and change the remote using the Activities tab and selecting "Customize Buttons" I get a screen that says "Unable to Display Content" and then a "Next" button. If I try to customize buttons through the device tab, it seems to work correctly in the program, but the buttons are never updated in the remote. It did this with both the 7.4.3 software and the 7.5.0 version as well. That's why I thought it was something to do with the age of my remote.
