How do I activate BS2 from steam BS1?


Recommended Posts



I recently reformatted my hard drive and had to reinstall DCS world and all the modules. The other modules have been fine (a-10 and huey) but I'm having problems with black shark. I own BS1 from steam, and bought BS2 upgrade off the website and I don't remember having any trouble with it the last time.


However, whenever I enter my serial when prompted when loading a mission, it will not accept my serial, and says it's wrong or mis-typed. Am i missing something, and can anyone give me some assistance? It would be greatly appreciated.




EDIT: here's the exact error message:


The system requires the correct Serial Number of the application to perform this operation. The Serial Number entered is wrong or mistyped. Enter a valid Serial Number and try again.
