Activecaptain stopped working

I really want to love this app, but recently its been acting funny. Of late, it wont allow me to log into ActiveCaptain. I deleted and reinstalled the app and its still failing to login.
It shows me logged in on my phone, but it stopped working on my iPad, which is what I use as a repeater from my Garmin GPS onboard.
