Error accessing plex share

I have Rockstor set up primarily for the Plex rockon. I’m very new at this, a computer savvy friend set it
up for me and I’m trying my best to keep it going. At some point recently it stopped working, like it couldn’t access the files. I decided to dig around and noticed I can’t open the files share in windows, and I get errors in the Rockstor ui when I try to change any of its settings. The disk is fine, as another rockon and share that use it (Transmission) still work and I can open them as normal. At this point I’d be fine just being able to recover the files we’ve collected, but I can’t seem to access them.

Linux: 4.10.6-1.el7.elrepo.x86_64
Rockstor 3.9.1-0
