Upgrading MAM 2.0 to MAM 2.5

Hi,

Last week I upgraded the MAM 2.0 to MAM 2.5. I installed the latest Package Support in my middleware (SP13), and follow the upgrade documentation for MAM 2.5. But when I deploy the MAM 2.5 on the mobile device I can only see the USER VIEW MANAGER option. MAM 2.0 since to be working fine with all the options available.

I contacted the people responsible for the backend system and they ensure me that their system is updated for MAM 2.5. Any help will be appreciated.
