ok well you might want to download a fresh copy of VAM, so you can see a "clean" install and reference it. Basically you are missing several Key folders for custom content installation. You removed the Custom Folder which is where 90% of the content is put, like morphs, cloths, sounds, scripts, textures, levels, etc. That is prob the reason you have those errors, you are missing all the content that the scene requires. Like, if you open the scene's ".json" file in note pad, you can litterally see all the content it uses and normally where it's suppose to go. The Var system will look for those files listed in the json.
same thing with the timeline plugin, its trying to find those morphs in the custom folder, which isn't there. So, you get an error saying it can't find it.
