Problems opening Interactplayer on IPAD

Hi, does it say anything on the login screen, like that the password is wrong, or does it show a black screen after you log in?

It just won't open  It doesn't say that the password is wrong.  It just continues in the window thinking.  Later, It said that I had "oops too many registered devices"  Ezra has cleared this out before but I have never been able to open my app on IP4 since the IB4 updates.  I am creating it on my IMAc and IP will open there, but not on my IPAD.
