I am a little confused by the question. Are you able to get into the database at all?
If so, you can do a file save as and just rename the database whatever you want it to be. If you have started the creation of a new database and would like to copy the tables over you can do that as well.
One way is to just import them using the import wizard.
Copy the table structure, follow these steps:
1.Right-click the existing table name in the Database Window of the original database and click Copy.
2.Close the database Window and open your new database.
3.Under Objects, click Tables. Then, right-click the database Window and click Paste.
4.Enter a name for the new table, choose Structure Only, and then click OK.
