You got me, was just grabbing at straws. When you say Microstudio is working fine, then you're able to burn cdg's from Microstudio, right? If so, I misunderstood the problem.
What kind of files were you originally talking about? I assumed you meant cdg's.
I guess I can't understand what the Karaoke files are doing in Excel. (letting my ignorance show through).
