Perpetual license upgrade?

I recently purchased a new computer with Windows 11, I have a perpetual license for my Draftsight purchase, but it is stuck at the 2016 version. It turns out that it isn't compatible with Win 11. I was wondering if I can purchase a one-time maintenance upgrade on my existing license to get it to work with Win 11. I have tried contacting support at Cleverbridge where I originally bought the license, and they basically told me to contact Solidworks to see what they could offer. One of the links they sent me brought me here. So, I'm hoping that someone from Solidworks/Draftsight is listening and can help me out with this. Thanks!
