Visual Composer Help

I had someone else working on my website previously and had downloaded the Visual Composer plugin from WPBakery at the time. Unfortunately, this person is not on the project anymore and I need to update this plugin in order for it to work with my new Woow theme. Problem is: I don’t have the account credentials. If I repurchase Visual Composer, am I going to lose all the information that has been on my website up to now?

No, as long as they weren’t using a modified version of VC, all data on the pages will be safe.
