I just downloaded the latest version of Draftsight (V1R3.2) for OS X. My computer allowed me to install over my older version, but when I tried to open it, I was informed that my computer didn't support it. I was unable to find the earlier versions in the Draftsight website, so I downloaded it from Sourceforge or CNET (I can't remember which.) I installed the older version (V1R2.1) but I wasn't allowed to open it due to an expired license. Although I'm likely to have a new Mac at some point in the near future, I have a lot of drafting to do over the next few weeks! 

Any ideas? Thanks!
