Cannot log on to My Book Live fr Mac

Installed the required software for remote access but I try to log in I get a message that my security settings does not allow it.  I checked that my security settings have enabled Java but still cannot access it.  This message appears after i key in the passwod for the network drive.  Can someone pls help?  Thanks.

Are you able to change the java security setting to medium? Also you may try reinstalling JAVA.
