Older versions are not available.
Though as I said in the main thread, I loaded in to my ALCD test world today and updated the script and it booted up fine and all screens were still being updated correctly. The script hasn't been updated since 20th of March and as far as I'm aware there haven't been any game updates in the last few days so there's no legitimate reason for it to suddenly stop working overnight like that.

Are you running a beta version from Steam?
Do you have experimental mode turned on and in game scripts enabled in your world settings?
Have you tested any other scripts to ensure they are still able to run?

Try unsubbing, restarting steam, resubbing again to ensure the local steam copy of the script hasn't become corrupted somehow.
