System.Data.SqlClient.SqlException
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_*". The conflict occurred in database "aspnet*", table "dbo.*", column '*ID'.

Uh oh... Not sure what this means?  This one is pretty easy. It means your referenced table doesn't have a corresponding row with a matching key.

Fix: Either manually add a row via SQL Server Management Studio or add a row via code.
