Can't send for eSignature - Missing FEIN but have form 4852

[DragonFire]

My client's company went under.  She has not been able to obtain a W2. I've checked the box for substitute W2 and created a form 4852.  There are still two errors on her W2 - not have the state tax ID and not having the FEIN. I tried to send for eSignature, and of course it failed. 

It is permitted to eFile with the form 4852, but I can't proceed forward with the errors on the W2.  

Any suggestions?

You wont be able to EF the return with a 4852, may as well mail the whole thing to the client for signing and mailing.
