Microstudio is not recognizing some kmas files

[chrosme]

Perhaps theres someone else out there having the same issue and trying to figure it out how to fix it.
My problem is that I want to burn a cd using my kma´s, but some of them are not accepted for my microstudio.
I have over 8,000 tracks, some imported by hoster from hdd files (bins) and the
mojority from cd+g cds.
I can use Microst. to burn both types of files imported (hdd or cd tracks) but some of the cd+g tracks cant be recognized or imported as well as some hdd files.
What could be the problem? any Idea people..?
