The text, ntext, and image data types cannot be compared or sorted, except when using IS NULL or LIKE operator.

I have looked at the SQL which is being generated and it looks like the problem is that an equals is being used in the SQL to compare an ntext field.  I am posting the SQL below.  The only ntext fields in the table are Email and SendMsg.  There are no text or image data types.  It looks like the Email field is the one causing the problem....I have highlighted the part that I believe to be in error.
