ok this is my first guide so I hope it helps you.
Ok first download Crossover 6.0 (you are going to have to pay for it in 60 days)

now you are going to want to make a bottle call it vent,

Now comes the fun part, we are going to have to download a file called msgsm32.acm this can be found here: http://www.soundcard-drivers.com/drivers/7/7019.htm
you are going to need to follow the directions and either make an account w/ these guys or look at about 5-7 ads that you can just cycle through before downloading
when you have that file you need to open up your bottle page again, and select Open C: Drive in Folder

and go to windows\system32\ where you will put msgsm32.acm

and click on system.ini (open it in text edit)
