Quake Injector with vkQuake will not work, “couldn’t spawn map” – From /r/Quake

So I have tried using Quake Injector and I have had nothing but issues. First off, I have the Settings option for executable as vkQuake.exe, and I have the Quake directory selected as steam/steamapps/common/Quake. I have tried to download over a dozen different maps, and each time I hit the Play button, it loads vkQuake and the console throws out the error “Couldn’t find map x.bsp”.

I have tried making different directories with the PAK files in an id1 folder, I have tried using the base quake.exe as an executable in the Settings, I have tried putting Quake Injector into my actual Quake directory in the Steam folders, and NOTHING works. I have tried to find an answer to this question, and I can’t find a single helpful answer, article, or piece of documentation anywhere. I am at my wits end – I’m used to modding Doom, which is as straightforward as can be. I’ve had nothing but trouble with this, and there’s little to no documentation or straightforward tutorials anywhere that are helpful whatsoever.

Does anyone know how to get this working?
