I have a problem with the sound. There's no music in the game. I've tried turning the computer's volume up and the game's volume up but it doesn't work.
Sound Doesn't Work
Download a windows version of a newer beta, version 1.90 doesn't work well with XP.
Thanks for the link but that didn't work. The MIDI player I was using didn't work for some reason but thanks anyways.
Owing to the fact that ZC uses an external library for sound, there isn't a whole load the designers can do to fix this. As suggested above, try a windows version of ZC.
Also, I'm going to move this topic to ZC Discussion. You're more likely to get help over there than here in the bugs forum.
...and I went ahead and edited your post to remove the extra formatting the bugs forum had added.
