Didn't received pre-order code

[CoverJagger]

Updating my situation here:

I received my 20 digit registration code today via e-mail from DigitalRiver along with an 18 digit code (which I don't know what is for, maybe for the pre-order bonus item Caith Sith doll pet?). But, like many of you guys out there, got the "The entered code is invalid." message.

Here we go again.

Updating again:

So, after getting the invalid code message, I remembered that I logged in the Mog Station yesterday and saw that there are a place to register account services. Well, I tried to register the code I received today and guess what? Gotcha! Service registered!

Today at home I'll try to log in the game to see if everything is ok. Wish me luck, guys!
