I've never heard of that error message before, and in my experience as a tech with TWC, cable cards are pretty crappy in general. While I'm sure there are plenty of people who don't have any issues with them, I of course, am on the phone taking calls from people who say that every couple of days they lose half their channels and have to unplug their tv and pull out the card for a few minutes and then reconnect everything.
There are apparently a lot of compatibilty issues with certain brands of cable cards and TVs but I haven't noticed a pattern that I could put my finger on.
I really have no advice for you about the PPV issue you're having as I have never encountered that particular problem either.
As far as an IPG (interactive program guide) goes, as the name suggests, they are interactive which does mean that two way communication is definitely necessary. The set-top boxes can only hold a certain amount of programming information and anything after a few days out is requested by the set-top on the fly from the provider. Cable cards aren't really popular where I am so I don't have much experience with versions and revisions and such but I personally have never encountered a card that supports program guide data.
I'm sorry I couldn't be more helpful to the specific problem you're having but I hope it lends some insight into the world of cable cards. I'd be happy to try and answer any more questions you have.
