Hi, open a terminal (Applications>Accessories>Terminal) and try installing the program with

sudo apt-get install package
*replace package with actual package
If you get the same error message try reinstalling apt

sudo apt-get --reinstall install apt

Try manually reinstalling apt. Go here and download the correct version of apt (http://packages.ubuntu.com/search?keywords=apt&searchon=names&suite=all&section=all) and once downloaded double click on it and reinstall.
If that does not work I am all out of ideas.
