is this your first time installing fMobi?? if you do then install Mcsp aswell.... if not the first time then revoke this apps from your facebook acct & invoke it agains...
I'm kind enough: https://www.sugarsync.com/pf/D6747279_84_8879735719 For info, I also had some issues with fmobi v2. So I install fmobi v1.4, start and login. After that v.2 just worked.
