Hi Nanette,
Sorry for the trouble!
The best course of action is to troubleshoot Local by Flywheel so you can import your sites into the Local Lightning beta.
Can you try opening Local by Flywheel and provide details of what’s happening or where you’re getting stuck? Also, can you provide your local-by-flywheel.log file? See How do I retrieve Local's log file? for instructions on how to do so.
