Lost all data on my material library

When I opened my lightburn today it made me reset up my laser info. Never done that before and would not let me continue until I did. After that my material library settings for my current laser are gone and I have not been able to find them even after using the back up option. When I go back to before today nothing changes. Is there another way to find my info. Thanks

As I understand it the material library is saved to your computer wherever you specified.
Hopefully a search for a .clb file will locate it.

Thank you, the only file I found was from today after it got messed up and is now blank. Ill just have to start over
