Hi There. First post on this forum, though regrettably I need assistance, if you will

I am attempting to patch my Final Fantasy XIV: ARR, but to no avail. It Takes 2 hours+ to try and download the 75MB file, and still fails with the errors [30413] [10009] [10019]

How can I resolve this error and be merrily on my way to install the game? My internet works perfectly fine everywhere else (in fact, our telecommunications provider basically upgraded the entire city not too long ago to faster ADSL - working even better than before)

Any advice would be greatly appreciated. Thanks in advance!
