gINT-MASTER LIBRARY FILE

Hello, 

I am new to gINT V8i Professional and Geopak V8i SS2.

Regarding specifying the library file in the system properties; I see in the help that the Master Library is managed by administration but the library file above it is required.  If I leave the Master Library file blank, it does not seem to impact gINT operation.  If I leave the Master Library file blank, will that cause me problems downstream?
