Molla Theme not working and no response from the author

I purchased Molla theme on Themeforrest but I´ve been having a lot of issues with no answer from the author so far.
My site is currently really slow. Molla theme is not compatible with the latest version of Woocommerce. The pluggins are huge and don´t fix any of my issues, and on top of that there is no customer support. I`ve written comments, nothing, also tried through the support website, doesn´t recognize my account. So I am loosing trust in Molla so far.
I need to fix all of these problems as soon as possible.
If someone can help me, please reach me (removed)
