invalid cd key?

MP cd-key issues, how to resolve them


Right Dark if you can, can you move this into the MP issues read only, it can stop loads of threads popping up, or will atleast give you a quick answer, as MP is now in the support section too.
-----------------------------

You're getting the error message:
"Login failed - invalid CD-key"

Right this is how to resolve (with thanks to various posters)
You cannot change the cd-key ingame anymore (most likely for the protection against illegal games), so you have to do other things.

Open Start
Click Run
Type: regedit
Now go to this: "HKEY_LOCAL_MACHINE/SOFTWARE/SEGA/Medieval II Total War"

Now you'll see a value representing the CD-key. Change it to what it should be. You could have done the following wrong:
-Don't type spaces
-Do type the "-"s
-Don't use "o"s use "0"s
-Type everything (except for the numbers obviously) in capital letters

Now it should work, if it doesn't let us now ... preferably in the MP part

do that, re-enter the key and see if it works

if it doesn't, uninstall the game, delete all traces of MTW2 in the register and install again
