I was trying to perform the the fix found at this link http://www.omgubuntu.co.uk/2012/01/how-to-make-google-earth-look-native-in-ubuntu

It requires you to delete certain files from the /opt/google/earth/free folder and then add some new ones that you download. I deleted the files but the links to download the new ones were unusable. I was using gksudo nautilus so trash was disabled meaning I could not restore the files I had deleted. I the tried to go to the Google Earth website and reinstall it. I downloaded the .deb but when I tried to install it it gav me an error message saying "cannot install ia32-libs" I tried installing this via terminal and it gave me an error message saying

chad@chad-Lenovo-G570:~$ sudo apt-get install ia32-libs

How do I fix this?

Now I am stuck without a functioning Google Earth. How can I fix this?
