Can't view office file

[shinju]

Hi Stephen,

I do fresh installation and now i can view file office, but i can't view file office 2007 with extension *.docx.
I try to add mimetype manualy in config.php but after i add the command, the web can't be display just give me a blank page.
How to add mimetype in the config? i also try the command in mimetype.php and not work either.

Thanks,
Shinju
