[bloggerDev] can't get user secured data using oauth

I'm creating a web application that is able to cross-post posted
photos from my site to blogger.
I'm not using Zend Library coz it is a huge library, 20+MB , so i
used alternative one.
Library : http://code.google.com/p/oauth-php/

I already have a valid access token
BUT,
always got this error

" Token invalid - AuthSub token has wrong scope Error 401 "

I have tried it on OAuth playground but it has the same result.

Please help me guys. thanks in advance :(
