Playing RGT files

Have just got hold of a Tyros. Have downloaded some registrations which show as RGT files. Cannot open these with WM Player.
I also have Real & Quicktime playrs installed.
Can anyone tell me how I can open these files.
Any help would be greatly appreciated.

The forum for the Tyros is the next one above this one at: http://www.synthzone.com/cgi-bin/forumdisplay.cgi?action=topics&number=39&SUBMIT=Go
We will be happy to see you posting there and you will get help there as you need it.
Best to you,
