Wp Bakery Activation issue

I purchased a theme calle electrician and it comes with WP Bakery Page Builder.
The Plug-in is asking me to activate it but when I try to activate it i am not able to activate it no matter what I do.
The Theme’s support is not giving me a clear answer, I don’t seem to be able to activate it unless I purchase a separate License key!
More money and added expense!

I would appreciate some assistance with this so that I can work on my site building.

Thank you,
Sparky
