Replace new license in old license

I have a website built with the WoodMart theme, and it’s been live for over a year. I’ve been regularly receiving updates for the theme, but recently I encountered an issue. A few days ago, I updated to WoodMart version 8, and after doing so, the design of my website broke. Additionally, I’m unable to update WPBakery. As a result, I’ve purchased a new WoodMart license and now need to replace the old license key with the new one. please help me
