How can i enable the "Chinese Translation" in Ribbon?

Dear all

I would like to know how can to recall the "Chinese Translation" tabs under
"Review" for MS PPT 2007?

I got such function in MS PPT 2003 and found it was really useful but i
could not find this function anymore in 2007. I searched the help and it
suggested me to use the "Translate" function under "Proofing" tabs. I accept
this as a solution before but yesterday my friend shows me he got the
"Chinese Translation" tabs under "Review" that can translate the document
within 5 second that was the same speed in PPT 2003.....

I checked and confirmed that we both got the "Chinese Translation addin" and
both displayed under "Active Application Add-ins" under PowerPoint Options.
But i still missing that tabs in Ribbon.... What things i shall do to get
back my tabs....please help
