Luckily, I keep a copy of that version (wonder why you need that old version, isn't latest version is better). You can send me an email to tuanpn@joomdonation.com and I will send that version 2.1.0 to you
I need it to find out the customisations that you guys did and then upgrading the customisations to the latest version. I now had 3 programmers who were unable to upgrade to v2.4.3 as they couldnt find out the customisations that were done.
