I purchased drive and then I registered (With the same email)

Alright so I guess I made a mistake of buying Drive and then signing up. It's all on the same email but it doesn't show my account as premium or whatever, and I can't access the drive forums. Any help?

 

If u have linked your account and the purchase of the alpha on the same email u can go to the email that gives you the link to download the game. At the bottom of the email there should be another link which sends u to activate the alpha with your existing forum account. U will need to then go to the email that was sent to u about activating your forum account and in the middle of the email should be these lines:
your username is: (whatever your username is)
activation id: (should be a series of numbers and lower case letters)

copy and paste your activation id in the appropriate space on the page that the link from the email (the one i stated at the start of this post) sends u to.

U should then be allowed full membership! hope this helps!
