Unfortunately, it's impossible to download an updated version of the software since there is no official website to download it from. The only thing I have found is a website where the JASCAP can be downloaded, but that's it. I have downloaded the software and it's not working on newer operating systems. You will have to install Windows XP through VirtualBox in order to run the software.
After you setup a virtual machine, copy the software to the virtual environment and launch it.
