Missing Files!!!

Please help me i have tried almost everything on Groove Agent 4 still i get in cubase 8 pro the message 50 Missing files
It’s working good except the missing file related to the library
In Media Bay I get red dot notify me of the missing files such as GM drum kit
I would be very happy if someone could help me I paid for this still Can’t use it properly

I’m having a similar issue instead I know where the missing files are, point to the folder, scan but Cubase just ignores them.

Something so straight forward is just giving me headaches. Every now and then I organise my sound library, move folders & rename accordingly. For cubase to now act dumb like it’s blind to the sample files even when I point to the correct folders to scan is beyond frustrating.
