Pro Sites Division by zero Error

On my pro sites pro upgrade checkout page, I am getting this error:
Warning: Division by zero in <path to wordpress>/wp-content/plugins/pro-sites/pro-sites-files/lib/ProSites/View/Front/Checkout.php on line 102

In addition, the pricing tables are not showing up. This is preventing a plan from being selected and prevents any upgrades.

Edit: Forgot to mention that this started occurring after the latest pro sites upgrade.
