This is a support forum for the WordPress core software, themes distributed here, and plugins distributed here.
We don't support commercial products here for good reasons: 1) we do not have access to that code nor want access because 2) we do not want to deprive developers of the income they get from supporting their products.
It's not for us to interfere with the business model of developers. We want to encourage them and see that they're wildly successful. Honest.
This theme, by the way, is free.
Yes, free to download elsewhere is still commercial even though you didn't pay for it and it's not hosted here.
If it's something trivial such as a small CSS adjustment and you share the link to your site then people often help. But in this case the software isn't working for the OP and that's something that needs to get handled by the theme author.
