[Failed to get authorization data. Error code is: 500]

Thanks BIGNEWY! That worked for me.

 

 

[Failed to get authorization data. Error code is: 500]

Exactly the same problem here. I updated the open beta installation. Then I tried to start the program and I got the error 500 message. I continue, and then I am asked valid serial numbers for the products I bought. I skipped these question and end up in a black sceen with the DCS logo.
