Hi Mr. Gary,
the basic "problem" is S775/S975 are
newer than the Genos. (Genos was introduced in 2017, S775/S975 in 2018).
In general, Yamaha keyboards are only compatible to Regiistrations of older models.
Make sure that the current Firmware V2.02 is installed on your Genos. If Genos still does not recognize your original S775 Registration files, you can try to convert the S775 Reg files into to Genos Reg format using the "Yamaha Registration Manager" (YRM) by Murray Best.
Note: Be sure to download and use the "
YRMSpecial" version:

Best regards,
