I am attempting to create a new database from a backup file of an old database that is still in use. At one point I was able to successfully restore the database, but had to delete it later after attempting to overwrite it with fresh data. Now when I try to restore the database I get an error that the database is in use. I am certain to specify a different name from the old and have even attempted to give it a different name than the one I was giving it before. I have also made certain to rename the data and log files to something other than the old database.

This is the stack trace for the error:

Restore of database 'Database' failed. (Microsoft.SqlServer.Management.RelationalEngineTasks)

We have tried restarting the SQL server to close any possible calls to the database, but this did not correct the issue. I have checked the 'overwrite' and 'close existing connections' boxes in the restore wizard, but these also have not corrected the issue. Any other tips on how to correct this issue?
