Loading-failure lottery

The issue can be found here: http://www.creationbytz.net
It works with other themes: Haven’t Tried
It works when I disable all other plugins: Haven’t Tried
Meta Slider version: 3.3.4.1

The Metaslider on my homepage fails to load roughly once every 100 times. I’ve seen it happen in various browsers and I can reproduce it in Chrome by simply refreshing countless times in a row (or clicking the logo which does the same but faster). Sometimes it takes forever to occur, but trust me, the problem is there.. In my computer logic, if it works once it should always work, but this seems like a lottery. Changing themes is not an option for me. I haven’t tried disabling other plug-ins, but again, if it works once, why shouldn’t it work every time? When it fails to load, my cursor has this loading-icon, indicating it got stuck somewhere in the process. Usually the slider will appear after a while but the cursor will still have this loading-icon. There’s only one little piece of custom CSS that applies to the slider, which is a negative value for margin-top, otherwise not much is going on.. What can I do? I’ve seen it fail with people on their first load, which really makes a lousy impression..
