I'm sorry the program isn't kosher with your PC system...
But be happy they even gave you moving memory of the u/s...the state of MS won't record u/s due to liability...(like if something is wrong with your baby and they don't diagnose it via u/s and later you use it as evidence that they COULD have kinda stuff)...So we only have still frames of Keegan in-utero...(GA let us record our u/s for Cameron)...
I hope you can get it to work...
