I have a membership authentication database that was working fine with SQL Express 2005 and I need to make it work with SQL Express 2008. I uninstalled SQL Express 2005 and installed SQL Express 2008 and now I get this error:
Server Error in '/Admin' Application.
Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.
I tried deleting the C:\Documents and Settings\username\Local Settings\Application Data\Microsoft\Microsoft SQL Server Data\SQLEXPRESS directory, but it didn't help.
