Administrator with no access to publishing

After creating a simple portlet, I try to publish it to MWS and I get the following error:

I’m logged as administrator and when I deploy it manually everything works.
Can you give me a clue to what I’m missing in here?

Using 8.2.2 in XP.

Hi Frederico

When the Designer asks for authentication during publishing, try “sysdmin” and Password: “manage”

instead of administrator.

Thanks Sakthi.
