Halion doesn't show/load presets?

Hi, I recently upgraded my DAW system; I had several vstpreset files in the old harddrive which I copied to my new drive in the same folder where my new vstpreset files reside; however, I cannot load them in Halion; when I try to load a preset, all I see are the new presets but not the previous one that I have copied in the same folder; I know that they are there; but Halion doesn’t see them. Can anyone please help?
