Premiere Pro 2018 does not load media from "shared" drive (Mac)

Hey guys,

Just upgraded from Premiere Pro 2017 to 2018 (version 12.0.0) and all my projects no longer open - as the media is not capable of loading. All my 4 hard drives are external and are on my network - which is Mac network (shared drives). Premiere does not load the medias. Premiere Pro 2017 had no issue with this.

Any input would be greatly appreciated.

Also is it possible to go back to 2017 version?

Thank you
