mp3+g (two files) changing so microstudio can read them

[nmothers]

I have several karaoke songs on my hard drive, they are two files mp3 and the .cdg, how can I put these on disc using microstudio as the program does not recognoise the .cdg file, I also have MTU's convertor program and tried to convert it to a .bin file and then change that file via windows explorer XP to a .cdg but I can't do that, you can only change the program that it opens with ie microstudio and it still does not recognise it. what am I doing wrong, i have these songs on my pc and i am dying to try them while i am out but can't get them to disc.
