Unable to join the session as all players were not on the latest version

I never used the free trial , I had bought the early access pre order and so it was just there for me . That sucks man . I feel your pain and I wish I had an answer for you . Maybe try it on a secondary profile ? Like make a new one or use one already on your system  to download the trial ? Sadly youd have to pay the 6 dollars for ea play to acquire that  trial but it might allow you to play. Ea sucks for real .
