To get the option to log in offline, you need to disconnect your wi-fi or ethernet cable. You need to find that missing file that was rejected, its got the original EF data contained in it, I dont think you'll be able to EF a new copy of it.  Could it have been accidently deleted and sitting in Windows recycle bin?

Sounds like you may have a bad install though, and doing a clean reinstall of the program might be a good idea.  You wont lose your client data files.
