Can't download client?

Ok so I can DL the swtup file and start it, but then after it goes a couple versions in it stops and gives me an error saying: A problem occurred while updating. Please restart FINAL FANTASY XIV: A Realm Reborn. [11005][20641][20643]

So Uninstalled to reinstall and still can't fix it. Not sure what happened with the versions but something is not right there.

Perhaps antivirus is interfering?

nope I turned off the antivirus and firewall. It starts to DL but then errors out saying:

Unable to update patch files [11006][20819][20890][19900][3] SqPack:0x0-0x0-0
