Songs changing key while playing

[Debinski]

About a month or two ago I hosted one show using Hoster. I had some problems and haven't used it again since.
I had imported only my "DK's" (about 3-4 days worth) into Hoster 2.011. Then I decided to halt importing and try the system in the field to see if everything works ok.

Well about 1 out of 4 songs had an intermittent key change mid song. It was little embarrassing. Fortunately I was able to revert back to playing discs. Anyway...

Since then I have reimported the songs that had a problem that night as well as some others I found, and that solved the problem.

My questions are:

Is the key change issue in the kma file itself?
Will I need to reimport everything I've done so far?
Will upgrading to 2.100 solve the problem?

(Your "News" page suggested that you’ve done some work in the key changer dept.)

I presently have 2.014 installed.
