[ORD 2020 R3/Connect 16] Custom/network configuration vs. msconfig

I am trying to set up our Bentley Connect Workspace onto our network.

The first modification is a customized shortcut which includes the switch -wc"M:\Bentley\ORD\NetworkRedirect.cfg"

This file has one statement set in it:

#============================================================================
# Civil Organization Standard Location
#============================================================================

%if exists (M:/Bentley/ORD/Configuration/CustomConfig.cfg)
     %include M:/Bentley/ORD/Configuration/CustomConfig.cfg
     %include C:/Program Files/Bentley/OpenRoads Designer CONNECT Edition/OpenRoadsDesigner/config/mslocal.cfg
%endif

The CustomConfig.cfg includes

[General]
_USTN_CUSTOM_CONFIGURATION=M:/Bentley/ORD/Configuration/
%lock _USTN_CUSTOM_CONFIGURATION

[SetConfiguration]
%if !defined (_USTN_USER_CONFIGURATION)
    %if defined (_USTN_CUSTOM_CONFIGURATION) && ($(_USTN_CUSTOM_CONFIGURATION) != "") && exists ($(_USTN_CUSTOM_CONFIGURATION))
    _USTN_CONFIGURATION = $(_USTN_CUSTOM_CONFIGURATION)
    %endif
%endif
%lock _USTN_CONFIGURATION

_USTN_USERNAME = $(USERNAME)
%lock _USTN_USERNAME
SHR_USERDIR = M:/Bentley/ORD/Configuration/Users/$(USTN_USERNAME)/

%undef _USTN_USERCFG
_USTN_USERCFG = $(SHR_USERDIR)Personal.ucf
%lock _USTN_USERCFG

I am getting this error message when I try to open the software:

Exiting, M:\Bentley\ORD\Configuration\Users\personal.ucf not found, [c:Program Files\Bentley\OpenRoads Designer CONNECT Edition\OpenRoadsDesigner\config\msconfig.cfg], line 291

They aren't wrong...I do not have a Personal.ucf in M:\Bentley\ORD\Configuration\Users\personal.ucf. It is stored in M:\Bentley\ORD\Configuration\Users\mbloswick\personal.ucf
Which I thought I was defining in my CustomConfig and locking.

Without this, I can't get any further in checking anything else, because without the UCF, ORD (MicroStation) just exits without any further processing.

How confused am I, and where am I going wrong?
Thank you.
