Endless loop: ping.fm facebook app asks to install/is already installed

I have the ping.fm app installed on my facebook personal account. I have a couple of pages and am trying to link ping.fm to each of those pages. I already have one ping.fm account that connects to my personal facebook profile, as well as all my other networks. Now I have a new ping.fm account for a magazine I publish and want to link it to the facebook page for that magazine, which I administer through my personal account. I get stuck in a loop where ping.fm's facebook app tells me to install it, but it's already installed. Now what?
