I'm trying to run on my PC a web site that uses Umbraco (for development purposes). I restored on my local SLQ Server a copy of the production DB and for a few days the site was working fine. But recently it started throwing an error "Umbraco cannot start. A connection string is configured but Umbraco cannot connect to the database."

In web.config I have a setting for "reportingDbDSN", but I don't have that DB on my PC. I guess this is what is causing the error. Is there a way to create an empty reporting DB?
