The file you download is a tar.bz2, not zip or exe. You need to extract
it with:

tar xjf src.tar.bz2

Jon,

I think the Lattice web has at least sporadic issues with the download
there are several people complaining about the downloads not starting,
so I dont it the issue of not being able to uncompress .bz2

Antti

As mentioned  by Antti, its not issue of uncompressing tar.gz or zip
files, i am unable to get anything downloaded. just read the mesage
that i get whenever i click on any link. i even wrote to webmaster, but
its about a month ,and with 2 reminds, still no response from
webmaster.
