Here is what you need to check:
1. Where on your computer is the PAD file located? (run a search for .PAD because it may be in several places)
***It should be located in the following two places:
C:\Program Files\Parker\wInControl v2.8
2. Are the PAD files marked 'Read Only'? (Right-click on the file and go to properties).
*** .PAD cannot be marked 'Read Only', change to Read/Write.
