Channel Guide Suddenly FUBAR'ed!

Suddenly my Channel Guide seems like it’s for the wrong city. Done three channel scans hoping the problem will fix, but no luck.

The first column below is what I get from the channel scan before I click Add to Guide.

The second column is what’s there after I click Add to Guide and it’s done refreshing the guide.

I did NOT change my city.

I did send an email to support earlier asking to get a channel 45 into my guide (it wasn’t showing any guide data even though I receive a strong signal for it).

But now NONE of the channels are showing correct info!

How can I get this fixed???
