Update Query With Join

I am getting error of multi-part identifier could not be bound, but can not remove the error from my query?  SQL Server 2008

Update fafa
set fafa.uid = '100', fafa.logindate = GetDate()
From hellfire.uinfo.dbo.Diplomats fafa
Inner Join hellfire.masterinfo.dbo.FileFarce zzz
On fafa.Key = zzz.Key
Where zzz.empTitle IN ('IT', 'Manager', 'Supervisor')
And zzz.empNumber IN ('123', '456', '555')
