In Print Artist Platinum, to close the current project and choose another one without exiting the entire program, you can usually find an option in the menu such as "File" and then "Close Project" or "Open Project." This allows you to close the current project and open a new one without shutting down the application. The exact steps might vary slightly based on the version of the software you are using, so it could be helpful to look for a similar option or consult the software's help documentation for specific instructions.
