How can I re-download store manager for Zen Cart?

I am trying to figure out how I can redownload store manager for Zen-Cart. My computer recently crashed and had to reformat my drive. I have found my way in for my license information on your site, but I can't find a way to get at least the original version that I was running beings my update period has expired.

Thanks in advance and sorry if this is a duplicate request for some reason my email hasn't been pulling down all emails (yet another task to work on)..
