cck address module :validation error

Hello Everyone,

I have added cck_address module .

I have added content types as address through "admin/content/types/add".

After that I have created field as country and done all data settings.

I have check only country field in "customize fileds to use".

But when I am going to create content as address then I am not getting any values in country dropdown
and getting this validation error-->

"Address field is required.
City field is required.
ZIP field is required.
Illegal value for Country's State field. You must select a State from the dropdown list."

Although I have unchecked all these fields except country.

I am not getting what to do.

Your Help is needed.
