Serial number invalid

[Neomorph]

Hello, I've bought on Steam yesterday, the P-51 module. The activation with the Steam serial number worked perfectly. But if I want to sign me in multiplayer I get the following error message; serial number invalid. I own the modules BS2, CA, UH-1H, A-10C and Mi-8. For there were no problems.

 

I ask for solution of the problem.

Hi. I'm not sure it is a solution, but you may want to try that;

 

Go to http://www.digitalcombatsimulator.com/

Log in and go to the Personel Section / Licensing.

Enter your P-51D's serial key and check the "Bound to" line.

 

You must see your login name there...
