Tracks won't display on map or appear in Recorded Activities.

I moved a recorded track from my older GPS Map 78sc to my new 66i.  When I hook the 66i up to my computer and launch BaseCamp, the track appears in the Internal Storage Folder of the 66i, but I can not get it to appear in Tracks, Recorded Activities, or on the Map page of the 66i,  The file shows as a Track file in BaseCamp, and shows on the map in BaseCamp, buit I can get it to show up on actual GPS.  Any one know how to get the damn track to show up on the map on my 66i?
