Not sure I find all of the necessary info in your post. It is now July, so possibly you figured it out. The Nevo is going to require new programming to work with any of the equipment which has been changed.

Did someone design and program the remote for you? If yes, you will need to talk with them and hope they still have your program file. The file will only work with NevoStudio Pro application on a Windows PC. The devices which have been replaced need to be removed and the new devices, Uverse, receiver, etc need to be added.

Good luck....
