Lost the free channels

I dropped my Dish sub last year, but left my VIP722k hooked up. Until this past week, I could still get some of the free channels, such as FETV and Inspiration, and some of the free HBO's and such (when those were in free mode). As of a few days back, ALL of those have vanished from the guide, and I no longer have access to them.

Are there any others that had the same situation, and have also lost those channels? Maybe they rolled out a new firmware or something?

Just wondering...
