Failed Login, Computer tied to another account

[JK2597]

So I got the FAF client today, I registered and got an account, (account name: "JK") verified it and everything. So when I try and login to it I get a message saying: "This computer is tied to this account: tungulria. Multiple accounts are not allowed. You can free this computer by logging in with that account (tungulria) on another computer."

I have never used FAF or made an account for FAF on this computer or any computer prior to today, and I never used or seen that username/account name in my life. So, can I do anything about this? Am I doing something wrong? Is someone, somehow using something of mine?
Also if it is needed, I bought Supcom FA through steam (I also have the original Supcom, bought through steam as well).

I have a similar issue and I need help.

My little brother has been using my PC while he was home for the summer and he created a similar username: DarkLight02.

Now he's back at school and my PC won't let me login: DarkLight, because it is locked to his username. How do I fix this?

Can you log with his account on another PC ?

[DarkLight]

No, I just have the one.

"tungulria" is now free. You can login on the PC that was using it.

Same for DarkLight02.
