Connecting to a local database at the moment, it will result in an error
when you try to register/log in a user. You must change the Connection
String in your DAL (DataAccess.cs) constructor to match your connection
string.

Example: (Mine)
Data Source=XCYTHER;Initial Catalog=SportalDb;Integrated Security=True

The Data source, and Catalog should change to whatever database is on
your local computer. The catalog should remain the same as we are all
using the same database. The DataSource, however, MUST change to your
'Server name'
