Pandora has stopped working - DirecTV

I have a HD DVR receiver that has a hard wire connection to the internet. I have been listening to Pandora for quite some time through my receiver. I have an online account with Pandora. Pandora no longer works. I get an error message when I tried to connect to Pandora that says that there is a problem connecting to the internet. This not true because I can connect using On Demand to download movies and programs. When I connect with Pandora/Directv it wants me to enter a code. However, I cannot get the code when I try to go to Pandora in the Extras menu. How can I solve this problem?
