You're going to need a lot more specific that this... A LOT more.

When you say "her database stopped working" are you saying that the SQL Server instance isn't work, or that you are unable to access the database on the SQl Server? If the former, what do the SQL Server logs say? Do yiou have any error messages when you try use USE the database, or perform a query?

You should also know that you don't "open" a database (and most certainly not my double clicking it...).

P.s. I suspect a post in a day or two offering a solution on how to restore a corrupted database tool (even though the OP has made no mention of corruption), so prepare the spam button. 🙂
