Where is the channel guide I was using that shows My Channels?

More info needed like DTV sat service or DTV streaming, on the DTV receiver or website or mobile device.

I have regular DirecTV.  I usually use the channel guide on my computer that I linked directly to DTV.  When I went to check it, it's gone now and I can't find another guide that will list My Channels with what's on tv now.  Oh, and I have a receiver but sometimes I watch on my computer.  

There is another post on this, unknown if it is a temporary glitch as the new partner continues to move things to them as the only guide found is for the streaming side.

Ok.  TY for helping, Shannon.
