Can you install a NetScape on your machine?
If you do, you can download a trial version of NJstar from www.njstar.com, and then you can view and type into chinese. ( I meet the similar prob as you)
I don't know why, but it seems that NJStar only works fine with NS but cause trouble with IE.
If this way works, let me know, I can email you a full copy of NJStar.
You may also try to log into your own machine( domain-> choose your own machine name) to see if then you can download and install the chinese font for IE.
Hope that helps.
