The default LOC file that Groundspeak creates is "geocaching (x).loc, which CACH'EYE won't import because "it has a space in the name". You need to rename them all to import them.
I would suggest you try and fix this for the new release.
This should be fixed in maintenance release 1.2.1 which went online today. Now It's possible to import LOC-Files with default names created by groundspeak.
