I am not sure I completely understood your scenario. Can you please clarify a bit, are you occasionally renaming your columns in the database? If you do so, the you should always use the Update From Database Wizard to propagate the changes to the .rlinq file. If you just rename your tables/columns in the database, you will have problems during runtime if you do not propagate those changes to the .rlinq model so OpenAccess is aware of the metadata of your relational database schema.
We will get back to you with additional details regarding your account questions and the support procedures.
