I have been trying to do this ever since the patch came out.

After 2 days of this, I tried uninstalling XIV and reinstalling entirely + Heavensward. Now instead of failing to update the small 1GB update, Its failing to update ALL updated that have been released leading up to the latest. So now I am in an even worse off position.
Tried again and again over the next few days, No luck. Then two nights ago my sub ran out, I decided to just say to hell with it I quit. Then someone messages me on skype going "Hey! There was an update, everything is fixed now!"

So I resub, Install the game again, Get ready to update. and oh look~

So... No luck.
Going to try just installing ARR without HW to see if that is the culprit.
