Just receieved my Open Beta key code after trying non stop, was getting the same message since yesterday morning, 'Applications for the FINAL FANTASY XIV Open Beta Test have been temporarily suspended. Please wait until we are ready to accept new applications and then try again.' Tried 10 mins ago and got my key :D.
Hopefully they're releasing more keys for people who haven't got one. Unless it's just random pot luck.
Hope this helps.
