Could you try:
[list type=decimal]
[*]Click Start > Run
[*]Enter regedit
[*]A new window will open, browse to HKEY_CURRENT_USER > Software > MountAndBladeWarbandKeys
[*]Search the entry, serial_key_nw, make sure that the value is the same as your CD key. Also make sure that the key is separated correctly. Double click the entry and modify it until it is correct. Watch out for invisible spaces in the CD key.
[*]If you are done with that, close the Registry Window and start the game, connect to the server and have fun playing!

Thank you for your quick answer Vincenzo,
I have open the MountAndBladeWarbandKeys folder, but I don't find any "serial_key_nw"
I have try to send you a picture of my regedit but the forum don't allow me to.

In my regedit i have:
-(par defaut), with no data
-activation code, with the manually obtained code (8x4 caracters separated by a "-")
-hardware hash, with the machine hardware hash (3x4 caracters separated by a "-")
-last_module_warband, with "Napoleonic Wars" in
I have check all the codes severals times, there is no mistake in the codes.
I have try to create a line "serial_key_nw" with my key in there, but it doesn't work.
I am not very good in english, i hope don't have miss informations in your answer.
Thank you to help me.
