I live in Serbia.When I want to open a new account and choose 'Serbia & Montenegro',yahoo shows a problem.Why?

My dear Serbian sister,I know of this problem already.My friend tried to make an account and it didn't work.It is obvious that Yahoo is being run by the enemies of Serbia,trust me,this might sound dumb but I actually had many occasions where this proved right.They just don't like us (and Greek too),it is some kind of conspiracy against Orthodox nations.The other explanation is that Serbia and Montenegro doesn't exist as one state,so they have problems creating them separately,but that doesn't seem right because it has been around 3 months they don't allow Serbian users here.Weird.
