CB8P Mediabay, uplicate entries were found

Hi there!

After installing the new Cubase 8 Pro I now got this message every time I starting up:

When the mediabay attempted to mount the volume database on drive ‘/’, duplicate entries were found. Hos should this be resolved?? “Delete local database entries” or “Don’t mount volume database”

What has been change since 7.5 and what does this mean??
I have tried to follow both possibilities but nothing is change, I got the same message next time I open CB8P

Any input on this issue?

Thanks in advance!
