Did you receive all the monthly sub rewards during the required time? My sub lapsed for a day or two due to losing losing my card and having to order another one, thought I wouldn't be eligible for it. That was in the middle of the month though I subbed ASAP not expecting anything more than just access to all my toons and creds, I did get all the monthly sub rewards and was able to play it. Could be a bug, servers are gonna be offline again to be restarted so maybe that'll help. Also the in game mail you get is wrong, it's not in your mission log automatically you need to get from the mission console on your ship. Good luck
