Installation Issues for expansion Packs

Hello I am a returning veteran and I am also in the U.S Military currently stationed in South Korea. I downloaded a version of the game and got my account back up and running hoping to hop back into the game but unfortunately my main character is in whitegate. I am unable to install the expansion packs because I do not have the disks on me and I am hoping to not have to buy the whole thing and wait for a few weeks just to have it sent to me on base since I am not in the states.

Is there any way I can download the expansions without having to buy them or am I sol?

We apologize for any inconvenience, however the game client is not available for download from SQUARE ENIX. Installation will require the original installation media, or the digital download if purchased through a participating retailer. Again, we apologize for any inconvenience that this may cause.
