Cthulu 3rd party presets not available

Hey there, I got a little problem with cthulu:
I just downloaded a couple 3rd party .mid presets. I put them in the chords folder inside the cthulu presets folder. The preset folders containing the .mid are visible in cthulu, but the .mid files are not displayed and thus can't be used.
Would appreaciate if anyone could help!

mid files would be for dragging in to your DAW directly and don't belong in Cthulhu Presets folder. You could check with the 3rd party for more information!
