Co-op not working

Hi, I am playing Hidden and Dangerous 2 co-op, but I am getting tired of playing the same 9 original missions over and over.
I have decided to add mod co-op maps. Two things happen after I installed the mod. The game either lose all of it's missions and maps, or the game doesn't read the mod and keep showing the original maps.

I am running the game as administrator and I am installing the mods right.
Can anyone help me, I would appreciate it.

Regards.

All you have to do is:

1. download the CMP from here
2. extract it somewhere
3. copy "Maps, Missions, Models, Scripts, Sounds, Text" into your main game folder (it might ask you to overwrite some files, just say yes)

When you say: " the game doesn't read the mod and keep showing the original maps", are you trying to create your own server?
If you are, then you need to modify the file "mpmaplist.txt" to include the new maps.

If game doesnt show missions in game menu then there is something wrong with mpmaplist.txt 

Maybe this can help:
 

folder Orig_with_CMP has original maplist with CMP included and the file NEW_mpmaplist.txt has comments for equipment so you can make easy changes, just rename it to mpmaplist.txt to use it.

It looks like it was the mpmaplist.txt that was the problem.
Thank you very much, all of you
