Facebook app FAIL

I'm having an issue with my Facebook pregnancy app. I'm pregnant and I want to share the updates with my family and friends. Every time I try to sign up for updates, I get an error page saying: Oh no - there's been a problem! An active access token must be used to query information about the current user.

What does this mean and how can I fix it!?!
I really want updates and I find this to be inconvenient and a bit frustrating. :/
Have any of you experienced this problem?

Im having the same problem, did you ever figure it out?

No I haven't I think it's cause I'm using an android phone. Do you use a phone too or computer?
