MyDesigner Crashes when Adding Overlay

Thanks.   I typed  \\192.168.10.252\myserver when mapping a network drive and assigned it available drive letter R.   Windows assigned it to R and it shows up in file manager.   For some reason Windows dropped the \myserver part.    When I click on the share in file manager I can navigate to the files including overlays and I seem to have read/write access..  MyDesigner is configured like the attached picture.   Some progress but MyDesigner still crashes when I try to select an overlay to add (click on the button with the 3 dots. 

Could it be something as simple as removing the extra forward slash after myserver in your settings?

I added that for some reason.   Let me try removing it.  Thx

Removing the slash did not correct the issue.   Dang.

If that doesn't work, try R: now that you have mapped the network drive.

Thanks tried that but I lost access to my project files when I did that.
