Latest update to my WD EX2 ultra as stop me able to access library on server

Please help. I have updated plex server to PlexMediaServer-1.42.2.10156-f737b826c-MyCloudEX2Ultra_OS5.bin on my Wd ex2 ultra and I can not longer see my library. Is there an old verso. Someone can share that does work. I do not seem to be able to roll back.

Sorted. Found 1.41 and that works.
