Hi, I downloaded a copy of jazz jackrabbit 1, but i couldn't open the EXE file, so I 've downloaded the Xmas version, and I can run it, but the sound is quite bad, for example if u shoot the shot sounds two times, one time and then one more time, i mean that the sounds appear duplicated and too slow, the music is horrible with this bug... how can I fix it? and, how can I run the normal version?

Srry if my post is hard to understand, but my enlglish isn't very good.
