Although this topic has been discussed at length to eliminate problems, the "error message "File not found, or File name is inappropriate", has still to be resolved.
My findings are that both the TSV files and Registration files need to have any instances of COMMAS removed. From both the Filepath Column in the TSV file and the respective Filename in the RGT file.
E.G. From the 'Ballroom' category, 'Kiss Me, Honey Honey, Kiss Me.rgt', should read 'Kiss Me Honey Honey Kiss Me.rgt'
Notice the absence of the Commas.
I have done this with all of my files and the error has been removed so that the Genos2 can read the files appropriately.
I hope this is of help to you all.
