Jukebox Developer Needs Help

The developer of this script: https://www.gmodstore.com/market/view/EBeugCjARtW-D0G-yC6Ccg has an outdated addon, after Gmod's latest update it broke the API, rendering the jukebox useless. He told me that he's trying to reach out to the guy who developed the previous API for him, but it's been a few weeks and I don't think he'shaving any luck. He said he'll disable the addon if he can't get help soon enough - so that's why I'm promoting help here. Surely someone here could fix this guys problem? It's a fun script and would be a shame to go.
