WifiSpoof won't open after upgrading to v3.3

SweetP

This may happen when you skip updating to v3.2 before updating to v3.3 IF you have some rules configured.

the solution to get WiFiSpoof working again is this:
-locate and delete the rules file:
~/Library/Containers/com.sweetpproductions.WiFiSpoofApp/Data/Library/Application Support/com.sweetpproductions.WiFiSpoofApp/WiFiSpoof.storedata

restart WifiSpoof
(you will have to reconfigure your rules)

*Note - the file is located in your user Library which is normally hidden.
to enable it on macOS High Sierra

open the Finder
open Finder Preferences
choose the Sidebar tab
check the House icon with your username

older operating systems work differently and need a different solution:

open the Finder
click on the Go menu
hold down the Option key - the user Library folder should temporarily show for you to choose
