Any way to use an addon that was removed from the steam workshop?

Well basically, the “Colorful Weaponry” addon is not on the workshop anymore. Because of this, the .gma file for it will not load. Is there any way to make it load? I really loved the addon, it would be a shame for it to be unusable forever. I already tried to use the “Gmad extractor” but when I loaded in the converted addon, it didnt work. (the addon is a retexture for the HL2 weapons; it changes them to your physgun color). Thanks for any help. By the way, I apologize if this question doesn’t fit here. This isn’t a problem with the game itself so I just placed it here.

Extracting is the only way. Find out what went wrong and fix it.

I’m not too knowledgeable on addons, but I will try to look into it. If I can’t, I might just have to reupload the gma. The addon extracted to an addon.txt (I believe that is used for gmod 13), materials, models, weapons, and then the VTF and VMT files.

Not the place to ask for help, please see Developer Discussion, thanks!
