Hi,
Sorry for the delayed response.
1. Which type of project is it? Is the Live Preview working for any other files in the project or in any other project in the workspace?
2. Can you please share with us a screenshot of the editor area to help us get a visual?
3. Please share with us the .log file located in the workspace dir/.metadata/.log to help us look for any errors/exceptions logged. Please change the extension to .txt and attach it here.
Apologies for inconvenience caused.
