Here is how to setup the map directories to work properly with PCMSS.
1) To install the South maps, create a directory named "C:\MAPPagesSouth" and copy all the South map pages into this directory.
2) To install the Central maps, create a directory named "C:\MAPPagesCentral" and copy all the Central map pages into this directory.
3) Create a third directory named "C:\MapPages". First copy your Central map pages into this directory. THen copy the South map pages into this directory. When asked to overwrite, say NO.
