Thanks Fred and Derek.
This is not an issue with registrations. The issue is that I have downloaded some Styles to my laptop that I then put onto a USB stick. When I try the style to make sure it’s what I want I then copy the Style to a Style directory in the user area of the ( I have created a directory structure in User area). I then use the style from there. However, the Genos still wants to look for the Style on the original USB this is confirmed by the location noted at the bottom of the screen, off course, there is no USB inserted so it comes back with a data error. The Genos does occasional display reindexed x minutes ago what I was hoping to do was to reindeer manually so that once I remove the USB it make any changes to the directory structure in the User area the changes are then updated. It is also the same issue with Midi files.
If indexing is automatic as Fred you say, and that is the only way, then I guess I have to just sit and wait it out.
Cheers David
