>So, I went and deatach the database. But where it is now? It was called Credit and I can not find it now on my drive.
Your database don't figure into your Database tree at your SQL Enterprise Manager, but they are safe, you now only have your Separates MDB y .LOG files. Usually they are at (HOME(SQLServer)+"MSSQL\Data\YourData.MDF". To see it at your manager you have to Attach it again.
