But now!!!!!!!!!!
Please wait until the start of the early access period or official launch to access the game.

I connected directly to my cable modem to assure a solid connection, helped get past this error. BUT still got another error after download finished and it started "updating". I had to download via torrent for Beta Phase 4 and put it in a directory called ffxiv. I just moved the
"FINAL FANTASY XIV - A Realm Reborn" directory under Program Files(x86)\Square Enix\ where it should be by default and i finally patched with 8.5 hours to Early Access. Hope this helps someone else get past these errors...
