I had this happen to me today. I found that if I sent them separately (just do Federal return first) that one would work, leaving me with just the state return. I 'updated' Turbotax a million times to no avail, restarted, lessened browser security (per customer support suggestions). Finally, I downloaded the state again using the Online menu (and I think I did have to repay), restarted Turbotax, and it worked.
