Wrong account linked

Hello, I have already contacted support about this issue, posting here to doublecheck. I have bought the game when it came out, which means I am an alpha tester. Now, what happened is, when I saw that they are giving out the Steam keys to alpha testers, I clicked the link they provided, entered the order ID and ACCIDENTALLY made a new account. This account is manwelb (the one I made by mistake) and my primary one is manwelb6. Then I realized the mistake I have done, logged into manwelb6 and tried to link my account. Now, the thing is, it tells me I need to unlink my old account first and I do not know how to do that. Can somebody help me please?
Thanks

same problem here http://www.beamng.com/members/67112-nando1

 

your majesty, I have linked my account and im logged into steam right now, how do i update through steam?

 

Thanks a bunch! I salute you!

EDIT: Now on this account it tells me that the order ID is already in use by someone else and this problem is being caused because I accidentally entered the order ID in manwelb. My account is basically useless as of now, I cannot download the game nor get a steam key :/
Any help would be appreciated. Thanks.

 

Sorry for bumping here, but can somebody help please?

 

I have a feeling this is the wrong place to post, but I want to know how to change my account name. I want it renamed to "Kevin Hahn"

Thanks for any help,

Oh! It wasn't made by me! You could change it to "Kevin_Hahn" rather.
Also, I'm looking to change the name of my account, not merge with another.

Thanks for the help, Gabe!

Kevin

Edit: Great! Thanks you guys are the best!
