I recently began playing on the Gorath server and used the 14-day free trial. After the trial was up, I paid the $19 to continue access to the game. Now, when I paid I was informed that I had access to Lightspeed, Obi-Wan, and Rage of the Wookies expansions. By paying do I have all the content readily available to me, or do I have to buy each expansion? I question this, because I tried to go to Mustafar using my starship, and was told that I was unable to visit. Thank you in advance for your replies.

I figured it out. Turns out when I paid after my trial was up, I had access to the main game, Lightspeed, and Rage of the Wookies. I did not have access to Trials of Obi-Wan. Problem solved. Thank you for answering.
