i just downloaded and installed DCS World, Combined Arms, and A-10C 1.2.0. this is a fresh Windows 7 64 bit system with no previous DCS installations. i installed DCS World. then CA. activated CA with the serial i got via email. activation appeared to work, but when i log in to multiplayer (click connect after entering my user/pass), i get a popup message that says "invalid serial number". i copied and pasted the serial from the email, so i know there were no typos.
next, i installed A-10C 1.2.0. i used my old A-10C serial to activate it. no problem there. still getting "invalid serial" error when logging into MP.
i tried reactivating CA by holding shift while launching DCS World MP. copied and pasted the serial again, making sure there were no extra spaces or anything in the serial. activation appeared to work again, but i still get invalid serial number.
please advise, ED!
