CONNECT - additional dgnlib materials

I have a dgnlib for materials, he has always worked well with SS3, after you add the path to the MS_MATERIAL

Well, with CONNECT adding that dgnlib into the MS_MATERIAL, palettes and materials do not work, the computer remains locked for minutes at every small change of the parameters.
I tried adding the dgnlib in the MS dgnlib folder c: \ programdata \ bentley \ connectsharedcontent \ materials \

and everything works.

The dgnlib is on a NAS

how to fix?

ciao
