I have a huge problem.  I discovered that my admin role had a missing Mobile User role.  I went to add this to my Role/Groups for Admin and then when I logged in with my user name, then the only roles I had available are Mobile USERS, Support, and Sales.  I have no ADMIN role anymore even though I am setup for for those tab links under that group setting.  HELP, I am down for the weekend and can not do any work on customization.  Thank You!
