No TV signal after FCC Repack

[snarl16]

Our local ABC station was part of the repack on Saturday. My hd homerun tuner picks up the newly scanned channel fine but when I go into media center, it says there is no signal. I've tried rescanning and even did a full media center refresh to start from scratch. Does anyone know how to fix this?

I finally figured this out. In media center, I had to go in and unselect the old frequency sources. For some reason, it was showing both the old and new and the old ones had priority.
