Old posepack doesn't open in Sims4Studio... any way to fix it?

[angelkamui]

Hello! I found a very old posepack from 2015 which I want to access the clips and update to a newer version. I don't post The Sims 4 content, so the update is just for my personal use. I tried to open with the most recent version of Sims 4 Studio (3.1.4.9), but I get an error. The original creator last updated their blog in 2016, so I don't know if they're still active anywhere with another alias. Is there any way for me to open this after so many years? ? I have attached the package to this post. Thank you in advance for your attention.
