Cannot create SQL DB with same name as one just deleted

I am using SQL2012 and need to restore a test database.  The existing test DB would not allow me to restore data into it because it said it was in use.  So I went ahead and deleted the test DB.  But now it gives me error 1828 "Logical File Name Already In Use".

The new DB must have the same name as the one I deleted.  How can I get this DB created?

Thanks
