Campaign progress lost

Prior to buying the game, I had played the ea access trial of bf2, which allowed you to play through 3 campaign missions. As such, I could play through all three missions however many times I wanted. After buying the game, I proceeded to play up to mission 8, whereby I decided to stop playing and let my little brother have a play at the earlier levels. I came back to the game later, to find that the "continue campaign" button was entertaining only the second campaign mission that my brother had been playing and so, I decided to look at the mission selection page. To my utter annoyance, the only accessible missions were the first three that I'd played within the trial and while the game acknowledged that I had played it earlier and I had received the appropriate rewards, there was no other sign of my progress!

Please help, despite the controversy surrounding the game, I am rather enjoying it and hope to continue the campaign as soon as possible.

Best regards,
