Hey Gavin and thanks for getting in touch!
We’d be happy to help — but I do want to note that our pre-sales forum is used to answer questions about purchasing our premium plugins.
If you’re looking for technical support, it would be awesome if you could post your question to our WordPress.org support forum.
Or, if you already have an active license for one of premium plugins, will you please log into your account and post your topic to our premium support forum instead?
In the meantime, I do think this might be more a question for the theme developer since it’s more about whether the theme’s functionality supports a customer post type and custom archive templates. I’d recommend starting there and then opening up a support thread with us if the theme developer has questions that we can help answer.
Thanks so much!
Geoff
