Same here installed on the 10th of March and this morning no Pg. Called Voom twice and still no Pg. I have unpluged the stb, I have held doen the power button, Voom has sent a hit to my box and waited about 5 hours and still no Pg.
I was just installed early this evening and I do not have a program guide on either of my two receivers. I get channel names but no guide. I also had a lockup when channel surfing. It locked on the country music channel. I reset the box and when it came back up I had no channel names at all. Also, a favorite I had said was lost. Eventually the channel names did come back but of course there's still no program guide. Thank goodness for zap2it.
