How do I update Enfold?

Up front, I am not a webmaster – I use WordPress to manage my website and depend on it to do everything under the covers. I have read all the posts about the problems with the sliders and masonry, which I am experiencing at http://pointarenalighthouse.com/. Unfortunately, all the fixes seem to involve the person fixing it to know how to edit java scripts or run updates to the Enfold theme within the actual folder where the files are located. I would like to be able to do the Themeforest update through WordPress, but when I go to the Dashboard, Updates Enfold is not one of the options so I don’t seem to be able to update it. I also checked the Theme Options under Enfold, and it says “No Updates available. You are running the latest version! (3.3.2)” but according to the support threads Enfold is at 3.5.2. When I click on Check Manually it just takes me back to the WP Update page and Enfold is not listed there. How do I get Enfold to update through WordPress so I can get the fix for the slider/masonry problem?

Also, your screen shots for Themeforest and Envato are no longer correct, they look NOTHING like what the currrent sites look like.
