The DSA version 4 seems to no longer be available, and you need to subscribe to the author on Patreon for the latest version 5 software.

@varswd thank you for your guidance.
Can confirm the v5.0rc3.1 version (Patreon) fixes this error for me.

it's paywalled , you need the version 5 to edit . Down patching your game should work

[mooofin]

wait for the creator to make it open , hopefully soom
