Some people install ColorWasher, FocalBlade or LightMachine for MacOS X without administrator rights. As a result ColorWasher, FocalBlade or LightMachine sometimes have no access to the language files.
Here is the solution:
1. Select the languages sub folder,
2. Choose "Get Info" from the File menu at the top of your screen.
3. In the Info dialog go to "Ownershop & Permissions" and change all settings to "Read & Write".
