HI FredyLau,
Do you still have the product key for your Office 2007?
if so I guess you can try to download office 2007 online and put your product key in to activate it
Do you buy this office in a Box or it is a OEM version?
maybe you can try to contact Microsoft Hong Kong and ask them to send you the disc.

Please correct me if my concept is wrong
