The samples and the bank files need to all be in the same directory.  

1) Do not use the same filename in multiple directories on the hard drive, 
   as the program might inadvertently pick up the wrong file.

2) For better organization of sound files, create a new directory under 
   your preferred name, where you place all your Wave (.wav) & Pinnacle bank
   (.pbf) files.
   
   Example: Place all your Wave & Pinnacle bank files in the "c:\sounds"
     directory.

   Note: DO NOT put this under the directory "TBS PROS" - if you ever run 
     the "Cleanup" utility, it may DELETE them all.
