I'm on PC with Win XP. I tried reintalling it with the (optional)music zip now, and it is working. Or hasn't crashed yet at least.  Didn't do anything else differently- how strange but good. Doesn't seem very optional to me.

Update: I have downloaded the music now and put the zip in the content\packages folder, but there is no music. I can't get any sound effects to work at all.

And the freezing still happens- every time I'm about to battle! Help Please!

I'm having trouble with this and would love some help. I just installed UQM v.3 after a few troubles. It seems the initial content.zip i downloaded was 7mb not 12. So re-downloaded and it was all better.
Anyway, when playing the game continually freezes. If I try playing a melee, the ship chooser screen appears but when I select battle, a blank screen comes up and freezes. It also happened in the game when I went into hyper space and when I tried to have a melee. Any ideas???
If its of any help- I didn't download the optional sound and music zips.

I love this game- haven't played since the original.

  It was my Gravis Ultrasound fandom (anyone remember that piece of premium sound hardware?) that brought me into contact with SC2.  I had collections of Euro "demos", mods etc... that showed off the "GUS".  While combing the Euro demo/mod newsgroups I saw the TFB call for mod musicians to help with the SC2 project.  Of course I had to get my hands on SC2 when it finally came out because of the novel sound system and GUS support, but I didn't expect to be locked away for a couple of weeks getting through it.  I can usually walk away from a game to eat, sleep etc...

 I introduced my brother to the game just this year when I set up an old PC (P133 /w GUS Max) for our mother.  Sure enough he was hooked, but he didn't take the game seriously early and his saves look like he's almost out of time.

 If/when you guys manage to come through (porting old code...  respect!) it will be fantastic.  Not only will my brother have an excellent excuse for a restart, but I'll finally be able to play SC2 on my ISAless PC, and I'll be running Debian GNU/Linux (RMS twisted my arm) to boot!  Still pinching myself...
