My problem is lately everytime I play back a song I just completed, the red line that moves across the screen in the arranger stops and the screen freezes, but the music keeps playing but the sound is static, distorted, and it even skips. Its plays almost like bad or scratched CD. It seems it started happening when I started using and applying some of the audio effects to different objects and/or when applying the Mastering Suite before I burn it to a CD. I have windows xp3, Magix MM Mx Premium. When the screen freezes I cant click on anything as nothing will work until it goes thru this phase. What could be the problem and what adjustments do I need to make? This just started happening just a few days ago. I have 10 tracks on this partucular song.
