Attempting to log in today (first time after patch), and the launcher won't boot, yielding the error "Unable to download patch files. [11003][20402[19901][2]". I read a bunch of the other threads and tried the following:

-loosened IE internet settings
-changed firewall settings
-reboot router
-disabled firewall
-reinstalled game
-turned off razer systems (game boosters sometimes affect other apps)
-attempted ffxiv boot as administrator in standard, windows 7 compatibility and windows 8 compatibility

Still no success. I have played this game since 2.0 beta, and I have only had to reinstall once, the patcher normally works fine. I run on windows 10.
