KaraFun karaoke

Dear Karafun Team!
I have been using Karafun for long time ago and it's so good, thank to the Team of Karafun very much.
But I just have bought a laptop a week ago brandnew HP with Memory is 1GB and video card is Nvidia, it is running with Window Vista home premium basic, I installed Karafun version 1.16, then play it with all the song I made by midi files , it's worked fine but some songs worked fine, and most of song playing without intruments except drum track and melody track , other tracks are lost, but those song were playing very good with window XP.
I hope he team quickly to find out the problem and create a new version to solve it.
Thank you so much to Karafun Team.
