Custom ExtendedMemebershipProvider MembershipUser GetUser Object Instance Error?

I keep getting the error: "Object reference not set to an instance of an object." on the italic code below. It code seems straight forward, Intellisense is happy and it compiles in VS2012. The only problem is that it won't run in a browser without error. I guess the MemberShipUser doesn't want to play nice. Help!

Note: This code runs after clicking the Login 'Submit' button.

Q. How Do I get this method to return a MembershipUser?

public override MembershipUser GetUser(string username, bool userIsOnline)
        {
            var user = (from u in entities.Users.ToList() where u.UserName == username select u).FirstOrDefault();

            var member = new MembershipUser(this.Name, user.UserName, user.UserID, user.Email, null, null, true, (bool)user.IsLockedOut, System.DateTime.Now, System.DateTime.Now, System.DateTime.Now, System.DateTime.Now, System.DateTime.Now);

            return member;
        }

user  probably null,

wrap it in something like this and see if it runs:

if(user != null){

}

if it still runs then couple of things...
you are invoking the constructor, this article says you shouldnt be doing that..

check this out:
http://msdn.microsoft.com/en-us/library/System.Web.Security.MembershipUser(v=vs.110).aspx

its actually the object you use when retrieving a membership user e.g.
MembershipUser u = Membership.GetUser(User.Identity.Name);

its been a while since I used Membership, but in essence it is bootstrapped from the config (web.config) so you install the asp.net membership stuff or roll your own... take a look at the second link its got links out to examples...
