Hm... odd. I just tried and I was able to start one of my tests on mba.com, which is good and means likely a local challenge. The first step would be to open it in an incognito window. That sounds quite a few problems usually...

I am able to start it on another laptop, but not mine. Thats odd. I tried clearing cache and browsing data but still doesnt work.
