I still play BOTF.
Granted I use Ultimate Dominion Mod for it which has new ship models, some modification to the Galaxy map size, etc.
Multiplayer runs fine if the other party has the same mod of course.
If you want to use vanilla game though (no mods), then I suggest you find and download the latest patch for the game.
This is the website that has the patch, the game as well, plus the mods:
