Issue recognizing Chinese terms in termbase

I work from Chinese to English. I have just purchased a new computer and have a fresh installation of Trados and MultiTerm.

Unfortunately, term recognition for Chinese terms is not working on my new computer. I am getting a message “No results available”. I have never had this issue before.

The only terms that are recognized are the few terms in my termbase that start with a non-Chinese character. For example, 1月 (January) IS recognized. Any terms that start with a Chinese character are not recognized. 

I have tried restarting Trados, removing and re-adding my termbases, and reorganizing in MultiTerm, but nothing works.

I did a search and found that other people have encountered this issue in the past, but in my case, the problem only occurs when the term starts with a Chinese character,

Any suggestions gratefully recieved!
