It worked perfectly well for me though...?
Just tested it on my end so it's probably a temporary technical issue on your end, what device did you use?
I'm using IE11 on my laptop (Windows based). I think I have this problem ever since I started the Chinese-English course when the it has just launched...anyway thanks for testing :-)
Well, I was on PC and I'm using Chrome on Win7. Maybe it's a browser issue? Sites these days are more optimized for Chrome/Firefox than IE... You should give other browsers a try then :P .
