I believe the CF/SF issues are referring to the Combine Federal/State Filing program.  I'm having the same issues, Info Return System won't create the transmission file, or it it does, there are these diagnostic CF/SF errors and the when I attempt to access transmit electronic files module the whole thing crashes and shuts itself off. All transmission settings are the same as the prior years'.  

At this point I HAVE NO IDEA HOW WE WILL EFILE ANY W2s or 1099s.  

HEY INTUIT, CAN SOMEBODY PLEASE LET US KNOW HOW TO FIX THIS.
