Main Quest Disappears After Cape Westwind

I am a level 50 Dragoon that has completed the Cape Westwind Duty after receiving the Operation Archon mission from Minfilia. Even though I have completed the Cape Westwind duty several times, and Operation Archon is listed as "complete" in my log, I am unable to move on to the next mission in the main quest. The log directs me to speak with the Allied Communications Officer, but does not show up, even though I have exited and reloaded the game. Nor is there a Main Quest indicator on the map. Nor are there any Main Quests in the "Current" section of my log.

I've been experiencing this problem for about six months. Please help load the Allied Communications Officer so he can offer me the next quest. I am currently stuck at this point in the game and will cancel my subscription if I am unable to resolve this issue.
