UPDATE:
Using the companion Iphone App, I was able to get Pandora working again. First, know that even if you are an existing Pandora account user, you need to click on the option that says you are not from INSIDE THE PIONEER APP on your iPHONE...so select NEW USER. The selections you choose on the iPhone app will appear on your TV screen in the GUI interface menu from the VSX-60. You are then directed to
www.pandora.com/pioneer and given a code on the screen to input at that website to link your Pandora account to your VSX-60. You have to do this from your laptop or desktop computer. You might be able to do it from your iPhone or iPad, but I didn't try. I just used my laptop b/c it was sitting on the couch beside me.
Once you input that activation code, you will be asked for your existing account information--email address and password. Once inputed, your Pandora account will once again work with your VSX-60 receiver.
Turn off the receiver, turn it back on and access Pandora via the "input" select keys on the VSX-60 remote. When you choose Pandora, your Pandora stations menu will appear and the VSX-60 remote can be used to select the station of your choice. That's it...it works!
Hope this helps others. It worked for me.
