When I play the files in question back it is never the same note that sticks, which is why I thought that it might be something other than the MIDI file that is causing it.Since it happens when i go through Sonar and Media Player I'm sure it is not any setting in Sonar.I am running the Ketron through a Tascam US 428 into my computer.I'm not sure if that's the culprit.
I was on the Cakewalk forum and someone suggested I get a separate Midi to USB cable for the Ketron.
I found this on Amazon

I ordered it, figured it is cheap enough to give it a try.
As far as getting another version, that is probably impossible.One of the songs is King of the Lobby,Brecker Brothers, another one is Ebony Jam by Tower of Power.That's the stuff that I cannot sequence easily myself and of which there is very little selection on the web,unfortunately.
