Error 401 and 601 CE Upgrade

[Kendah]

Am having this issue and cant subscribe due to error 401

When I tried to log in I received following message via launcher:

No valid or active service account is available to play FINAL FANTASY XIV: A Realm Reborn.

Proper registration through the FINAL FANTASY XIV: Mog Station is required.

* Users participating in early access must also complete registration by August 30, 2013. Using the code enclosed with your package, please complete registration through the FINAL FANTASY XIV: Mog Station.

And when trying to subscribe:

An error has occurred.
Please confirm the status of any relevant options and then try again.

(Error code: 401)

Already sent a ticket to support.

Trying to register and pay for subscription, total of EUR4.00 got deducted and never reversed, full amount of subscription did though.

Using IE did not work as well.

EDIT: now am getting 601 Error. So cant even try to register a payment anymore...

An error has occurred..
