im about to lose out on a free rack extension simply because i have an older mac "ppc" that will not download and run 6.5. I also have a pc that is not connected to the net due to viruses. i have my ignition key auth for 6.5 but i cant get Rack Extentions. i really wanted pulsar. not sure what to due? i think the free plug-in ends Oct 1st 2012. hope there is something i can do, without having to buy a new Mac.
