Thank-you for contacting Slingbox Forum. I am sorry your remote is not working for you!
If the remote was working before, I will need to ask what has changed if anything? You will possibly need to reconfigure the set up at setup.slingbox.com at the home location.
Try the steps in this link, even though you may not have updated the software in the Slingbox:
Hope this helps with your issue.
Have a great day!
