i got it off the DCS website, i checked on the DCS website and no it does not display my Serial number ethier, it displayed everything but the serial number, i check in module manager as well nothing. I tried DCS World repair 3 times and nothing.
Okay so when i first bought DCS Flamming cliffs 3 it never came with a serial number, and it has worked fine ever since until update 1.2.7 came along and screwed me over, when i have the module enabled and login to the multiplayer it says "Invalid Serial Number". No i do not have a second account. So can you guys please help.
