plus dme

I tried to link two computers together with audio
patchcords while the system was on and running and a power
problem blew my mother board and wrecked my power supply.
I had dowloaded Plus Digital Media Edition after purchase
only thing is I lost it on the original motherboard and
Original OS, I went from xp home to xp pro and now have no
ms dme on my system. It is cheap to buy and easy to use
but I don't feel like buying it twice
