I'm on my phone at the moment so unfortunately I'll have to try that when I get back from work... Just curious, I've made no changes to my AV since it loaded fine the first few times. I'm using AVG free and have all my java up to date. This is also happening on magic farm 2 if that helps. Just your pack and Magic farm 2. :-/Let's start by the normal reason this happens. Temporarily disable any antivirus software you are running, then restart the pack.
