Hello, Carinachan2000,
We would like to inform you that we do not store videos from clients’ websites on our servers. Therefore, if you did not download the video, unfortunately, we do not have it either to provide to you.
As I recall, there was nothing overly complex in the setup. Please navigate to Appearance > Menus > and try editing the menu. You should not encounter any issues during this process.
If you have any additional questions or face any difficulties, please do not hesitate to let us know.
Best regards,
The 8Theme Team
