FlashPrint isn't limited when it comes to loading additional files or projects. If you've saved your configurations on the local disk or external storage, then go to File in menubar and then use those functions to locate the configuration files on your hard disk.
For additional help, you could also use the built-in user guide accessible at this address: C:/Program Files/FlashForge/FlashPrint/doc/Flashprint-UserGuide-en_US.pdf
This is the website to download the software in case you need it: http://www.flashforge-usa.com/support/downloads/
