inviting friends in the new emails

today after i received my email, i signed up with everything as usual and it said i could invite 3 friends. i left the page open while i messaged everybody i could and by the time i had 3 emails to put in, i pressed next and the session expired on me. ive tried to reopen the link to get back but its telling me ive already finished and have no way to invite them? im even seeing other people having this problem and some others saying theyve contacted EA and they said theres nothing they can do?? is that a joke. whats the point in them offering and then making the session expire in less then 2 minutes and having no way of inviting them again? please ea sort this out because its actually the dumbest thing in the world.
