Using backup application database with a new user

I'm having trouble using a backed up database.

I was unable to login to metabase so I backed up the and metabase.db.trace.db files. To create a new user, I reinstalled the jar file in a new directory. From here how do I access my old database? If I copy those two files right to the new directory and try running it, it takes me to the setup page for a new user and once the setup is done the data is not there. If I try this command
java -jar -DMB_DB_FILE=/Users/anthonyoverton/metabase/ metabase.jar
It takes me to a sign in page and my current user/pw will not work.

Any help is appreciated, thanks!
