Hi nmerali,
YEM V2.3.2 is far too old. I recommend you to use V
2.6.0. This is the last version that can be used with Windows 7:

The Packs that are already imported are NOT affected when YEM is uninstalled/re-installed.
If you have already a PSR-S975 Install Target in the YEM, to be on the safe side I recommend to delete it fist. Then export the Instrument Info file (.n27) AGAIN from your S975 onto a USB stick, connect the stick to the PC then, and import the .n27 as a new Install Target in YEM.
Then you should be able to import also
protected Packs (.cpf) that are made for the S975. Note:
Protected Packs (.cpf) that are made for OTHER models (e.g. for Genos, Tyros5, S770, S970, S775) can NOT be used with the S975.
Unprotected Packs (.ppf) can
always be imported and used with the S975. However, in some cases certain voices may not be compatible.
Hope this helps!
Best regards,
Chris
