I'm doing Module 4.8 and the Write It test is not wrking. What can I do

I cannot get the Test Yourself Write It to work properly. After writing what I hear and press Reveal - I am getting the answer to the previous word, phrase r sentence. I have super fast internet so it is not that. Is something wrong with the program? 

Gill: I just tried a phrase in Lesson 4.8 Write it. When I typed the response a yellow icon seeming to indicate the system is "thinking" started turning. And several minutes later is still turning. I think you are right, there is something wrong with the program. I tried a Write It test in module 2 and got the same (non) response.

At the risk of dating myself, it seems that 
the trouble is not in your set.

Hi guys - Sorry, this was a bug from a recent "behind the scenes" roll-out. Should be fixed now!

Hi, I'm also having trouble with the "frozen phrase" bug in Module 5. I tried it in Modules 3 and still had the same problem. It's definitely frustrating when one is trying to learn a new language!
Chao,

Hi Brittany - Is this happening on a particular phrase? Do you know exactly which lesson/s this is happening in?
