Just a quick update, I contacted their support team directly. They asked for details including our current version, the version we wanted to install, the new PC specifications, Windows version, and controller details. Within five minutes, they emailed me a download link (V6.9) along with installation instructions.
Overall, it was excellent customer service.
I have now installed the software on the new PC, and everything is working fine. I would recommend calling them directly, as I didn’t receive a response via email. Thanks everyone for responses and helping out. Thanks to everyone for your responses and support.
