If a map was configured on a different PC or if modifications were made to a map then sent to you, you need to be able to load it. To do this copy the file from the host PC: Go to Start > My Computer > Click on the drive which WSOS was installed (typically C:), Program files (x86) (if on a 64-bit operating system) > WSOS > DNPADVC > Copy the DNP map and load it into the same directory for WSOS to access the file.
