Today my site went blank. GoDaddy said it was due

Today my site went blank. GoDaddy said it was due to an update made to my theme, CoursePress Pro. They had to enable another theme for the site to pull up. I tried downloading the theme from your site and I was able to download, but the installation failed. This is not my first wordpress site and I'm very much familiar with installing theme. It failed.

On the WPMUDEV dashboard, it says the theme is installed, bu the theme is nowhere to be found. I need to restore my site. I've been putting a lot of effort to building the structure and I need to update courses. This is urgent. Please.
