Unfortunately thats not useful, ive been through it twice now, it doesn't effect the activation problem. Unless i've missed something major.
Logging into the serial number manager on the website my key is listed, and the product "[D] DCS: A-10C Warthog"
In DCS A-10C 1.1.1.1 i can launch the game, activate it and log into multiplayer no problems, by doing this I've bound my key to my account, and in theory can play multiplayer if there were any servers to join, i can also play single player.
However the problem is with the DCS World A-10C module, i can start the game look in the module manager and see my key listed for the A-10c. when i try to launch a mission with the a-10c it asks for me to activate A-10c. this is where the problems start.
if i launch the multiplayer part of DCS world it will ask for activation and i wont be able to, same as when i attempt to launch a mission in singleplayer.
However in multiplayer if i repeatedly fail the activation it gives up and launches the multiplayer part where i can then log in and join a server, from there i can only spawn in as the free Su-25, if i try to spawn as an a-10c it wont progress to the flight scene.
So to clarify:
1. launches DCS World
2. Looked in module manager, show key, my key is visible and matches
3. Go to missions, start an a-10c mission, front end closes
4. Activation prompt comes up:
if A-10C 1.1.1.1 is installed and activated, serial key is already in the box, i get invalid hardware code message.
if A-10C 1.1.1.1 is not activated i enter the serial then i get the "the system requires the correct serial number", invalid serial code message. (note this message is the same as if i'd entered "please activate this time" into the serial code box)
5. un-able to activate, game loads and I'm a spectator.
If i repeat with this with the key unbound from the DCS website it all happens the same way apart from #2 where the serial code would be blank.
Bear in mind i dont get as far as the log in to dcs world prompt, before im hit with the activation requirement, i've only been able to bind the serial code to my dcs account via the stand alone 1.1.1.1 a-10c install.
As best i can tell the link is for people who are logging into dcs world with an account that doesn't have their key registered to them (and the game is already activated)
On a side note many thanks for the help you're providing, hope this helps you make any more suggestions, or tells you if i've missed something big :doh:
and sorry for the wall of text, trying to make things clear as i can :)
