How can I download DraftSight Professional 2019 (permanent license)?

I purchased a copy of the permanent license for DraftSight Professional 2019. I recently had to reinstall Windows and now cannot find a place to download my licensed version so I can continue working.

How can I download DraftSight Professional 2019?

The DS website only includes a link to download the 2022 version, which I downloaded and installed. When I tried to apply my license to that version, it was unsurprisingly rejected by the online license verification tool.

I sent emails to

-- "DraftSight.Professional@3ds.com" which replied with an automated message telling me to contact Cleverbridge

-- Cleverbridge Customer Support "cs@cleverbridge.com" who told me to contact Draftsight

I need to get my work done. How can I get help on this ASAP?
