I have the same problem! I tried downloading BuddyFeed but that didn't work either. It's driving me crazy - Tamara, #TeamMarina

I've been OK, but it seems to happen about every two weeks or if I hit FF from too many different computers. - Eric - Final Countdown

Eric, that's interesting. I also login from my MacBook, my iPad and IM. Too many logins? - Jeanine W.

Sarah, I haven't tried any of the clients yet, but Tamara's comment makes me think that it might not help. :-( - Jeanine W.

Forgot to add that I can sign into my iPad fine. It's just the phone I get an error message on - Tamara, #TeamMarina

I finally got through on my phone. Not quite sure what did it but I'm in! - Tamara, #TeamMarina

Boo! Hope one of these suggestions helps... - Lisa L. Seifert

I like FFHound from my Evo. - Mathew A. Koeneker

Thanks, Glen! It was the cookie problem. - Jeanine W.

I also use FFhound for my iPhone. No problems. - huntur (hotspacho)

Did somebody say cookies? *tummy growls* - Lisa L. Seifert
