when I try to set up the database, I save it. Then open it and try to use it. It tells me that The connection to the data source “voice one” could not be established. Why
Hello,
You have not provided needed information. OS, specific LibreOffice version, which database you are attempting to use (Base has two delivered with LO - HSQLDB embedded and Firebird embedded).
What is the specific error message you are getting.
Have you installed Java (necessary for HSQLDB embedded)? See this FAQ
