Amazon access keys

All the post I’ve been reading on this subject seems quite old anyway when I try to load amazon’s access keys in shopping pages /options of dashboard it says Cannot load amtp-addpages-page. and under amazon S3 photo gallery / settings ,when I insert keys it says Invalid access key and secret .I tried renewing access keys several times with no luck and still trying with brain host and no luck yet and come to find out they have never worked. Is there any help out there.
