Few other methods are available for opening docx with openoffice.
One of them is from Novell. Go to

"http://download.novell.com/protected/Summary.jsp?buildid=GuM6LMM9SR4"

and follow the instructions. Probably it will work. But remember, it should only work with novell edition of openoffice.
I did not yet give it a try.

Last method to get docx files to make work with openoffice is there are few online file conversion sites like www.zamzar.com
Go to their site and follow the instructions. Although it takes a while, it works.
As my files were not huge, I feel easy with this method.
