mohpa wont load,no sound

[robo135]

i know this an old game,sorry about that.
i have searched,been through all the posts,all 54 of them.
my problem is.
i install mohpa,go to play the game.
click on single player.
play on hard.
then it comes up with the white marker to 100%.
then it goes back to the desktop.
also when i click to play,it goes throught the logos,but im not getting any sound at all throughout the process.
i did click on the setup before i started the game.
i have played this game before on my machine couple of yrs ago.
since then i have updated my pc.
i used to have a 2600 amd cpu.
i dont have trouble with any games,farcry,call of duty2,coduo.
i have bought this game,it is not a download.
just wondering if my specs are to high.
any help please.
my specs are.
amd cpu4000+
x1900xt
santa cruz s/c
winxp pro
2mb crucial mem 4000
lcd 21"
