CMS ASP.net 2 Error

Hi, I'm working with a content management system called SiteFinity3. It uses Nolics to connect to a SQL Server 2005 database. Everything was working great until i stopped the database for maintenance and restarted it. Now I'm getting the following error:

I've checked the connection string in the web.config file and all the settings remain correct. Can anyone help?
