Since you have the latest Microstudio, try this:
Open Microstudio, select one of the songs you wish to change and right click on it.
Select Rename and change the file extension (3 characters after the period) from BIN to CDG.
Then click on Keyrite to open it and see if you can see the one file you just changed. If so then go back to Microstudio and repeat for each of the song files you need to change.
