Contact form 7 SmS Addon

I have installed conact form 7 sms addon plugin and it was working until previous Friday when I tried to install the PLugin Another Classified Plugin for WordPress. Anyway, after that my conact forms are not appearing on the dashboard. I reinstalled the plugins and although it seems that they work, they dont appear on dashboard. Also the plugin for the sms is not working as well, although username and password are correct and I have available sms.
