I assume you have already done a proper Forum Search for your model number in case other people have already answered your question ?
If so and that didn't help then check out this thread: https://community.sling.com/thread/3300?tstart=0
Come back if it that doesn't help either.
Al , greetings. I found on another forum an answer that solved the problem. It directed me to a posting which had attached one of those bin files ( very likely created by you! ) , C2010, which made it work to a satisfactory level. It is generic but makes the buttons work, at least for me, quite nicely. Thanks for your usual support and happy new year.
