If you are upgrading from Wall v1.2 or higher, simply unzip !15WALL.ZIP over 
your existing Wall files.


If you are upgrading from v1.1 or v1.0, you need to do two things:

1) Unzip !15WALL.ZIP over your existing Wall files.

2) In your Wall directory, run 11TO12.EXE.  This utility will convert
   your Wall data file so it can be used properly by Wall v1.5.
