[X Nullable object must have a value.]

This has been the most frustrating year I have ever had using this software.   It continually gives me this message, no matter what part of the tax return I am working on.   Then it goes into "loading mode" and goes nowhere until I have to refresh.  Then I end up back in the interview page for the wrong person I am working on.   

I will not use this program ever again.   None of the options suggested above have worked and I am still unable to net file my families taxes.

This is the message I now get when trying to netfile

 

[X Nullable object must have a value.]

Why am I getting this message before I even start my tax return

Nullable object must have a value.
