I already have the code and I have a Square Enix Account, but I don't know how to apply for the beta.
Go into the STORE and then redeem code, on left side. Menu, on the bottom.
Once you redeem your code you'll be able to start the download process, it will be with your games. Then you download the client.
It will ask you to log into SE user name and password, once you are downloading, and accepting terms, then it will ask
for the 20 digit code.
Instructions for using your Promotion Code:
Step 1: Connect the PlayStationÂ®3 system to a broadband connection
Step 2: Sign in to your Sony Entertainment Network account on PlayStationÂ®3
If you do not have an SEN account, please register for one (more information on www.playstation.com)
Step 3: Choose Account Management>Redeem Codes
Step 4: Select Redeem Promotion Code - this brings up a screen to enter the code you have received
Step 5: Enter code and follow the steps on screen to redeem content
