Sounds like the issue I’m having. When both Clockwork and archilab packages are installed on my machine, I can’t load scripts with Clockwork or archilab nodes inside them. Sure enough, I uninstalled Clockwork and could open your script, and I then uninstalled archilab and could open your script, but as soon as I installed them together at the same time, I opened your script and it crashed.
I just created a post about it here.
There’s also this post which is related, but I couldn’t get the solution to work for me.
