Trying to signup to NORTON SAFE WEB, but receiving this error message = Error: 0528

I want to register my site so that it can be reviewed by NORTON SAFE WEB.

 

I am in Japan, and trying to signup from within Japan (if that makes any difference).

 

When I try to sign up I am receiving this error message = Error: 0528

 

There is no explanation of what this error message refers to, and there is no other information offered, apart

from the error message.

 

Can you please tell me what this error message is referring to, and how do I signup?

 

Please help.
