Error on updating to Enfold 2.4.5

Hi,
I backed up my website kramercommercialinc.com and then attempted to update from Enfold 2.4.2 to Enfold 2.4.5. I get an error message that there is some customization so the theme update failed. I restored the website from backup. After several cycles of this, I found a similar support ticket which said to try the update using FTP. The support reply mentioned to watch the video here: https://vimeo.com/channels/aviathemes/67209750
However, the video does not load when the linked is clicked. Also, I can’t find the video on Vimeo.
Please provide instructions on updating via FTP or indicate how I can successfully do an automatic update.

Thanks,
Michael
