Emailed link didn't work - other options?

[70mlbu]

I forwarded the 3.316 link to our show computer to download the update. Something happened in the process and the link doesn't work. I've been reading forum messages and tried to go to where we ordered the Durabook notebook with Hoster. I scrolled to the bottom and downloaded the 3.312 update but the 3.316 update isn't there. How can I get the new update? We don't normally use our show computer for email because of viruses. We have to forward the link and then open email to get just that one. What am I missing here?

Thank you,
Dave
