Appreciate any help. Thank you!

Hi there,

Looks like you're using VS 2010 instead of VS 2008? The latter version has a different web.config file than in VS 2008.

Either remove the elements Membership, Profile and Roles from web.config to have it fall back on the defaults of LocalSqlServer or take a look at Chapter 18 and Appendix B to see how to reconfigure these providers.

Cheers,

Imar
