How are you launching the game? From the CD-Autorun menu or from the Start Menu? Do you see the movie at the beginning?
I'm launching the game using the StarfleetOP.exe from the game folder. I have 2 seperate folders one for each server. The one for Strayy's tavern works fine, no problems to report there. The one for The Forge has no sound AT ALL. In both cases i do not see a movie at the beginning.
Your problem is the system registry.. you must launch the game from the folder you last install to.
Example.. I install the game to SFCOP folder and I install a 2nd time to the SFCOP2 folder.. my system registry now recognizes the game being in the SFCOP2 game folder.. so me trying to play from the SFCOP game folder will create game bugs..
In order for me to play out of the SFCOP game folder without bugging.. I have to rename SFCOP2 to SFCOP@Old.. or something like that and rename SFCOP to SFCOP2..
This will allow the game to recgnize the proper registry entries for game components and help prevent game bugs.
This should be the method of any game you have installed to prevent bugging when dealing with multiple copies on the same system..
Now if you want to avoid all the renaming, you can get the Mod Chooser.. this program allows you to have the original game plus 4 mods installed to 1 copy of the game.. 1 click switch to a different version/mod.
On mine I have Taldren Original, OP + v4.0, my Hardcore server, and that leaves me 2 empty slots for upcoming servers or self created single player mods.
You're doing it the hard way.. launching from the incorrect game folder and getting your game bugged up.
