Some campaigns won't start

[BlueRooster2112]

Whenever I try to start a campaign with Eriador, Orcs of the Misty Mountains or Orcs of Gunabad, the game closes without any message of any kind.

1. Have you edited any files?
2. Are you using any submods?
3. What Windows do you have?
4. Is your M2TW steam or non steam version?

My M2TW is the Steam version. I have Windows Vista and I have not edited any files or installed any submods

Other campaigns start when you try them, or it doesn`t work with just these camapigns?

Have you edited security BEFORE installing Third Age for your Medieval 2 Total War main folder ( the one in STEAM\ \steamapps\common\ folder) ?
If not, uninstall Third Age, delete any TATW related folders, go here and apply Step 3 from Section How to fix it.
After applying this step 3, install TATW again.

Spoiler Alert, click show to read: 

1. Install all parts of TATW (3.0 Part 1, 3.0 Part 2, 3.1, and 3.2) by using the ˝........˝ button to browse ALL THIRD AGE INSTALLERS to DESKTOP ( Don`t create any folder on DESKTOP, it will create its own folder named mods) . Find this mods folder on your DESKTOP, open it and inside you will find Third_Age_3 folder.

2. Then copy\paste the Third_Age_3 folder to the Steam/Steamapps/Common/Medieval II Total War/mods folder.

3. Then rename one of the Kingdoms campaigns to something else, like change americas to americas2.

4. Then rename the Third _Age_3 folder to americas. Finally, select the americas campaign from the Steam menu and the mod should launch.

Ok, I'll try that. Thanks!
