Nuendo 7 strange behavior

Hi guys i am new here…

I have a question…i have a few licenses of Cubase 8.5 and Nuendo 7 and all of them work with files and projects on NAS thru 10 GB network…

Sometimes when i open the project some regions are visible but i can’t hear half of region…just like it is moved to the right but i see it completely

Specially when i move whole project from NAS to another computer it’s a disaster…when i import from pool same thing happen but when i drag and drop particular file from win explorer into timeline file works normally…

Any suggestion?

THX in advance
