Some more info: First starter club kit I am trying to deploy

Other parts of error code not coping;

 1) SqlException was unhandled by user code

  2) The user instance login flag is not supported on this version of SQL Server. The connection will be closed.(Does option have to be turned on?)

My deployment server is SQL 2008.

After installing VS2010 I noticed SQL2008 R2 is now installed on my pc.(don't think this is relavent)

Properties of Database are in VS2010 is .\SQLEXPRESS, NOT SURE OF WHAT VERSION(2005,2008)?

Will keep prying to answer myself but any help much appreciated.

P.S attachdbfilename is in the connection string in web config
