broken link to blog or wrong link in WP Themefuse theme

1. ME:
Hi. I am not a developer by any means but I have created several wordpress sites in the past and understand some basic html. I don't touch CSS - frankly it's stressful and scary and the two times I tried it had to have my site restored from a backup. This is to say I can understand instructions if they are clear.

2. THEMEFUSE SUPPORT:
To put it in a nutshell their support attempts through the several tickets have helped me get pretty much nowhere with the issues I am having.

3. $:
I cannot afford to hire a developer.

4. WPMUDEV:
Perhaps WPMUDEV can help me get on track. We will soon see.

6. QUESTION #2

When I click on the Blog link in the container on the homepage (not in the menu) I am taken to a 404 page.

Somehow I have the wrong link in that container. Which is odd because my latest post is showing up there.
