'datetime2' error when using entity framework in VS 2010 .net 4.0

Getting this error:

System.Data.SqlClient.SqlException : The conversion of a datetime2 data type to a datetime data type resulted in an out-of-range value.

My entity objects all line up to the DB objects.

I found only a single reference to this error via Google:

Google result

After reading this, I remember that we did add 2 fields and then updated the entity model from VS 2010. I'm not sure what he means by "hand coding" the differences. I don't see any.

All I'm doing in code is populating the entity object and then saving. (I also populate the new fields in code) I populated the date field with DateTime.Now..

The important part of the code is this: ctx.SaveChanges(SaveOptions.AcceptAllChangesAfterSave);

The database is SQL Server 2008.

Thoughts?

The rest of the error:
