He wrote live folder so it should be the US server.
Logout and try to delete the file "AddOnSettings.txt" in your live folder.
Just to be sure you are changing the files in the correct folder (which the game uses) edit the file "UserSettings.txt" with a text editor and change the following lines from
Code:
SET SkipPregameVideos "1"
SET HasPlayedPregameVideo "1"
to
Code:
SET SkipPregameVideos "0"
SET HasPlayedPregameVideo "0"
Afterwards login again and you should see the intro video palying again.
If it's not playing you have found the files with the correct name but the game is using some other folders.
-> You should search "all your harddrives" again for the file "UserSettings.txt". Maybe it is somewhere in another folder as well and the game is using this folder then.
