Hi Sarah,
    I am sending this from Tapatalk so all seems ok this morning. If you have an iPhone and you get the error message turn your phone off and try again. I get the message sometimes but also when I use Facebook through my iPhone. Each time it tells me to contact the administrator. I just switch it off and on again which seems to reboot the computer in the phone.

    Hope that helps but shout if you still have a problem.

    Ann xxxx
