Data adapter configureation error

Hi everybody. I got a db in sql server and it has 6 tables inside it .One of
the table that i want to create a datagrid using visual studio .net 2003 is
called matches. Unfortunetly when i try Right-click on the DataAdapter and choose Generate DataSet
i get the following errors.The table matches exist in sql server 2000 with data inside it but
i do not know why i get these error. I be happy if some one help me fix this problem.Thanks
