Error Connecting To ASPNETDB - Cannot Open Database

Hi everyone, i have already created posts about this problem and im aware theres millions of replys, but i still cant get this to work and its driving me mad. The posts i have seen i dont understand?

 Im using the standard ASPNETDB Database, i have never opened up SQL Server Management studio, although i do have the express edition.

i have tried everything and i am totally stumped as to what to do. Heres my web.config.

It works in VWD 2005 Express, but not in WWWROOT or on webserver?

PLEASE PLEASE PLEASE Can someone help me!!!!!!!!!
