Trouble checking in for flight on I.pad

[Sue1]

Hi
I have an iPad and had no problems before.  I am trying to check in on line with Ryanair and after entering my flight number and details I clicked next and it has gone onto the next page but won't let me click next for the next stage.  I can see the next page on the screen but it is telling me that it is loading please wait.  I have tried several times and waited but won't let me press select to move on.  I have always used my iPad for booking and checking in so can't understand why not now.  Any help will be greatly appreciated.
Regards Sue
