HELP - OLCI Failure!

Hi all,
I've been trying to do OLCI for the past 50 mins or so and i keep getting this;
Unfortunately we are unable to check you into this flight at this time. Please go to the airport to check in at least two hours before your scheduled departure.
To save time at the airport, you can enter your Advance Passenger Information here.
I have completed the advance passenger information and everything else i can think of, anybody have any idea whats happening?
Thanks in advance
