MSSQL Database Connection Fails with Cannot open user default database

I was able to connect to this database last week.

I updated my ASP.net 4.5 site this morning and hit this issue. My site uses EF code first. After receiving this error, I tried connecting to the database using SSMS, but hitting a Login failed error 4064.

The errors I received from both the ASP.NET site and SSMS follow ....

________________________________________________________________
ASP.NET SITE ERROR - http://user1258.netfx45lab.discountasp.net

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Login's Default Database

SQL Username: user1258

This is the username I received in email. It worked last week. It doesn't work anymore.

According to the SQL error details related to this error, I need to alter my default database.

From the error exception URL http://go.microsoft.com/fwlink?Prod...er&EvtSrc=MSSQLServer&EvtID=4064&LinkId=20476

"Use ALTER LOGIN to change the login's default database. Grant CONNECT permission to the login."
