I have Ballistic Weapons installes, so when I try to start a server (even a normal unmodded DM), when the map loads, when I should see the map. It goes back to the desktop & says "can't find junkwarsounds", do I have to download the junkwars mod?

You should more or less just download Junk Wars 1.1 public beta, go to the download section, download it and install it, and that should work, unless you need to do extra stuff with servers (by server did you mean Instant Action?).

Thanx man.

NP, its what this forum is for.

Well now it says it can't find BCore.

I'm pretty sure BCore is a major BW system file.
Try installing, or re-installing Ballistic Weapons 2.0.

hmmm.. i'm guessing that somewhere it's wanting JW to be used somewhere..

try disabling any junkwar weapons in the BW loadout or swapper mutators, and make sure JW isn't enabled at all..

BW 2.0 comes with the JW patch, so if you don't have JW, then the patch shouldnt be installed..
