How to upload successfully (error [11006][20641][20643])
So i had the stupid error [11006][20641][20643] too and fixed it applying some of the stuff i saw here in the forums (some copy&paste, other made by me). I will tell you what i did and worked for me in Wondows 7.
Hope it works (sorry for my bad english):
1. Go to C:\Users\<my name>\Documents\My Games\FINAL FANTASY XIV - A Realm Reborn\downloads. Delete the ffxivpatch folder
2. Then in
C:\Program Files (x86)\SquareEnix\FINAL FANTASY XIV - A Realm Reborn\boot
replace everything there with what is inside this folder:
https://www.dropbox.com/s/dy6douu7m0ofuot/boot.rar
3. Go back to the main Final Fantasy XIV folder and right click it. Turn off the "read only" option and then click apply (it doesn't apply to folder so it will always appear back on if you check again, check a file inside)
4. Click the start button and type in the Run "windows firewall" and select the "Windows Firewall", then turn off both option you will see.
5. Turn off your antivirus
6. With Windows 7 type "msconfig" in START. In the general tab pick the option "Selective Startup" and turn off "Load startup items" and restart your computer.
7. Press f8 BEFORE windows launches and select the option that goes "Safe mode with networking"
8 (optional) Sacrifice a farm animal and give the blood to your gods
9. Open the Final Fantasy XIV client AND NOTHING MORE. DONT DO ANYTHING WHILE IT UPLOADS. Wait for it.
It may take several tries. If you get the error just try to upload it again in the "safe mode with networking" until its done. You may need to re-connect to the internet.
Good Luck.
