Me too!
I just got my Voom yesterday. I had guide info about an hour after the install. During the night, both of my boxes got the software upgrade to 5.68. I had to reboot a couple times after the update. Since then, neither of my boxes has any guide info. Both say (no info) for all programs. It has been like this for 7 hours now since I rebooted this morning at 8:30am. I can watch all the channels fine, but with so many in the VaVaVoom package, it takes a long time to surf them all and see what is on!
I'm not seeing anything about a trip count on the setup screens. So I guess I'll just call into Voom and see what they have to say.
