Vocabulary page in Chinese

Thank you very much for extraordinaire work, Mark and other staffs.
I have a problem on the Chinese vocabulary page. When I add a new word in “add a Term” box, I see the following page.

Unhandled Exception

An unhandled exception was thrown by the application.

Also, on Lesson page, I was unable to LingQ a word “面包” or others.

Thanks in advance.
