I have been using Solsuite 2003 since I bought it in 2003. I lost it a couple of years ago, I forget how. I contacted Solsuite and they kindly sent me the software and activated it for me, free.
Yesterday when I tried to play it, the program had stopped. I contacted them again to be told that 2003 is no longer available and I should buy version 2011. I looked in my Hotmail archives and found an Email from Solsuite containing activation code for Solsuite 2009. I downloaded 2009, but the activation code no longer worked.
I assume Solsuite is trying to force their customers to buy the latest version. Sorry Solsuite, I will not do this on principal.
