It was still possible to get the latest Sonar Home Studio for free a couple of days ago, it still seems to be working.
Read this thread, post #16 has everything you need to get SHS put into your Cakewalk Account for free.
http://forum.cakewalk.com/Any-Possibility-of-Getting-the-Newest-Version-m3717194.aspx I would download the installer and run it manually so that you can choose to install the 32 bit version, it seems that the 64 bit version may have some issues opening older work files, after installation you'll then need to do an offline activation, it's a little confusing but not hard at all.
Good luck!
