You need to generate the database on your local computer first and then upload the full application including the database to the server side.
The error appears because your database does not exists ( or it is corrupt or it is not uploaded into correct location : APP_DATA folder of the application ).
ASP.NET can generate such database but only if you are running it on your local computer.
After the database is generated then you can upload to the server.
