cannot modify transposh automatic translations

Hello

I’ve recently installed Transposh in my wordpress (3.5.1). I’ve activated automatic translation, and allowed only administrator to modify the translations done by robots.

The problem is that I cannot modify any translation, in spite I have the administrator role. Only when I activate “anonymous” I can translate everything well.

When I try to translate something as an administrator, any text with a yellow icon, the server inform me:
“Server’s message: Unauthorized translation”

I’ve tried to create other users, with different roles, and to allow those roles to translate, but I always obtain the same message. Only anonymous translator works.

Any suggestion?

Thank you very much!!
