ping.fm not updating my friendfeed account

ping has stopped updating my friendfeed account. even though it shows up under recent posts as having made it to FF, it's not actually there. I don't know who is to blame, but seems like Ping is at fault for reporting success without verifying

update: I just removed friendfeed from my ping profile and tried to add it back but it says it cannot authenticate. i'm definitely using the correct login information.
