Memo field returning Null values

I have an SQL query that pulls data from an ODBC connection to a system DSN I have set up.  Everything works fine until I try to add one more field.  The field is listed in the database schema as a 'text' field with a limit of 8001 char... so I am assuming it is like a Memo field in Access.  When I add that field, all the fields are returned as Null.  I know there is data in that field because I can query it in Crystal and get data, but when I use that same query in VB it comes back Null.  Help!
