E6K Versions?
 

I purchased a TII with a Haltech E6K a few months ago. The tune on it is ok, but I wanted to change it up a bit, and I plan on turning up the boost in the near future too.
The guy I bought the car from lost the disk he had with the software on it, and just told me to d/l the program from Haltech's website, which I did. I tried to load it up yesterday, and I got an error saying that I needed a later version of the software. My question is, where can I download this 'later' version, and do they mean later as in older, or later as in the latest version available?

I know the PFC and Microtech fairly well, but the Haltech is new to me, it seems so old school its crazy. Any help would be appreciated.
Thanks guys!
