Cubase LE 7 - How to change the language?

I want to change the language back to English but I can’t find it anywhere
I’m using PC and I know people said that I can change it at "Preference’, but when I click on “File”, that option appeared to be grey and I can’t click it.
Can somebody help me please? I’m not used to reading simplied Chinese since I’m from Hong Kong :neutral_face:

Inside Cubase go to File, Preferences, click on General in the left-hand column, and then you can select “Language” on the top right corner of the screen.

Thank you for your kind reply
but I don’t know why the preference button appears to be grey and I can’t click on that
