Upgrading a 2 year old version of Hoster

[dspins]

My version of hoster has gotten old and now requires that I pay for a new upgrade. I am also moving hoster to a newer computer with a bigger hard drive at the same time. My question is, since you need your original copy of the software to upgrade, how do I upgrade on my new computer if you no longer have the version I originally purchased available for download on your website? I am searching through all my old downloads and am not sure if I saved the original one as I have not found it yet. Just courious if this is going to be an easy fix, or do I need someone there to post a copy of the 3.xxx software I started with.
