Java Certificates - HELP!

[PMBDaKing]

I wonder if anyone can help.
I'm trying to install LimeWire, and part of the installation process involves installing Java. When it comes to installing the package 'ca-certificates-java' it comes up with many messages saying that there was an 'error adding...' At the end of the installation, I get a message telling me to check my internet connection or installation medium. My internet connection works, so it must be the installation medium, but I don't know what to do about it.

Thanks.

System>administration>synaptic> in search box type sun.You will see list of packages.Find your installed java ( I believe it is sun-java6-jre)and mark it for reinstall.During reinstall you have to accept Java license.
