Okay just want to say I am running Windows 7 so I have no clue if this will help, just gonna run down the giant list of everything I did that worked before and then finally did (maybe one will work for you)
1. C:\Users\<my name>\Documents\My Games\FINAL FANTASY XIV - A Realm Reborn\downloads. Delete the ffxivpatch folder
2. Go to
C:\Program Files (x86)\SquareEnix\FINAL FANTASY XIV - A Realm Reborn\boot
and replace boot with a working copy.
*Boot Link*
3. While there I click back to SquareEnix file, right click Final Fantasy XIV, turn off "read only" (it doesn't apply to folder so it will always appear back on if you check again, check a file inside)
4. Turn off any and all firewall or protection services you are using. I have AVG and Windows Firewall both off.
5. Sacrifice a lamb and offer the blood to your god
6. With Windows 7 (and this is apparently in support as well) click Start, in search type "msconfig". In the general tab, turn off "Load startup items" and restart your computer. You may need to "reconnect" your internet if its wireless.
After trying step 6 it worked for me. Good luck to everyone
