Problems with visual composer.

Now I have installed a new version of theme Forest Camping Village wp, every thing seems to run ok but, I have a problem with the visual composer plugin and I wonder if the reason is because I don’t have a license. Is it possible?
I can’t edit with it

How do you b it have the license?

If VC came with the theme then author would be sure to check that whatever version is in the theme update works properly.
