This problem will be solved by CN5.2.2, however you are also able to solve it by changing Privilege.
OK, let's start to fix this problem.
Pls open system preference and open below 3 folders and change the privilege to "Read&Write" as attached file.
Check:
-Shared folder
-Library folder
-Preference folder
(/Users/Shared/Library/Preferences/com.EIZO.ColorNavigator/)
We found that the privilege is automatically changed to "Read only" by installing Adobe AIR (included in Adobe Creative Suite4).
