I was a Spotify premium user. My credit card got stolen, so I had to enter the new card to be Premium user again. Spotify works well on the PC, but the ipod touch, which already have 15 playlist just keeps saying I need to become a premium member. I try to click the "upgrade to premium" in this message, but no result. Wifi works ok, I have tried to connect it to the PC-still no results. Seems Spotify does not recognize this device. What do I do??
