I get the Preparer Code does not match error almost daily, sometimes multiple times a day.  This has been going on for 2-3 years.  I re-enter all the information and it holds for a while and then, deletes again.  No consistency in how long. We operate on a network with a data server.  At two different times over the past couple years, I've spent the better part of a day each time with tech support, only to be told they can't figure it out.

Has this problem been solved for others? 

I see it periodically pops up on this board.
