Z3ta+ 1.5 Crashing Reaper [DAW], legacy software recieving no tech support, what to do?

Hi there. I've had to sign up to these forums to ask for some advice. I recieved a copy of Z3ta+ 1.53 from Computer music magazine a couple of months back and had been experiencing crashes around the time. After a complete uninstal and slow re-instal of everything to try and find the cuplrit I never got round to re-installing Z3ta and had experienced no crashes since. I've recently re-installed Z3ta and without fail reaper will crash and become non responsive, grey out and hang indefinately until I reboot the computer. It will crash within about 30 seconds of me initializing an instance of Z3ta. It will also crash immediately if I attempt to change to a different sound back by clicking a letter along the top. I'm at a loss as to what to do. Computer music magazine has told me that I need to take the problem up with the manufacturer, and Cakewalk are no longer providing technical support for legacy software. My only option left is to come here on to the forums and state my situation. Any advise here would be very greatfully recieved. I've been getting in to Rhino which I've heard is very similar to Z3ta, I've also been checking out a lot of info about Z3ta+2 and from what I've garnered Z3ta is a beast of a synth, which only compounds my frustration in not being able to put it to any use. What am I to do?! Thanks in advance for any replies.
