If I remember correctly there were some MIDI files that did not play in some DAWs. The MIDI file headers were not compatible. I think Sonar had this problem with some MIDI files. The solution was to load the file into something else, in your case Reaper, then save it under a different name and then the new file would load in the DAW.

I hope this helps.

The manager asks, "do you mind waiting a bit?"
I said no.
"Good", he said. "Take these drinks to table 3"
