I tried logging in to FFXIV today, but every time I tried it hit me with either a 90002 or 2002 error.

I've tried troubleshooting this problem with all the usual advice like restarting my computer, uninstalling and reinstalling the game, disabling Large Send Offload, rebooting my router, changing my DNS settings, temporarily disabling my firewall, etc.

None of it worked, and now when I try to start the launcher, it says "Unable to download patch files [11003]". I'm currently in the middle of re-downloading my game again, but I'm worried it will just interrupt my download again and hit me with the same error.

I've been at this for hours now, please help!
