Spirit and Scribe themes both load miserable slowly

I recently signed up for Wpmudev and have spent most of the time being extremely frustrated. I requested a refund but was told to create a support ticket, which turns out to be the forum. I don't want to publicly list my URL on the forum, so I chose "other/not listed".
I started using the Upfront editor and my site immediately slowed to a crawl. It's gotten so bad that I can't even load the upfront editor. And, My site takes over a minute to load. I've tried multiple computers, browsers, and Internet connections. Please help.
Thank you
