paradoxbox Posted July 7, 2017 Share Posted July 7, 2017 I tried to update and run DCS for the first time in 3-4 months today but got an error message once DCS loaded: Invalid serial number with the serial number of some module I have installed. All my modules were purchased here on this site or on steam. What's going on? Link to comment Share on other sites More sharing options...
paradoxbox Posted July 7, 2017 Author Share Posted July 7, 2017 Update: DCS was for some reason using an old serial number for Combined Arms. I sold that copy and bought a new one recently with a new serial. Updating the serial again seems to have cleared the problem for now. Link to comment Share on other sites More sharing options...
