Did you already remove the battery for 2 minutes and reinstall. Still scrambled screen?

Next = Use a default file from .ccp and load it to the remote. Does the remote respond? Is the screen still scrambled?
If not, could be your file you made is corrupted. If it's still scrambled, then go to the next step.

Last = Do a complete factory reset on the remote. 1) Pull the battery out. 2) Hold down "ON" and the "MUTE" buttons while reinserting the battery.
