Two things,
your media folder names do not look correct – each should be computer name then ending in sequential number.
eg
machine.1
machine.2
(a new folder is created each time Avid reaches the limit of 5000 files)
Secondly as you arent working from Avid storage you need to enable alldrives in console, this will allow Avid MC to read media from network drives.
Once you have done that, delete the two database files mdb & pmr whilst no one is accessing the media and your machine will rescan and create them.
