Thank you for contacting the answer forum, I am sorry to hear that you are having a problem with the remote not uploading. I do have a question on what exactly you mean. Is it stuck on the loading IR code? Can you not find the correct remote? Is the remote not loading when you hit the icon on Watch.slingbox.com? If you could get this information to me so I could try and correct the issue for you than we could work towards a solution together.
Please help me help you,
