Vehicle addons cannot be loaded
So I've been trying to get some vehicle mods working, but after several hours no modded content will load. I've installed all the required tools (OpenIV, ScriptHook, ScriptHook V .NET, ASI Loader, OpenIV.asi, and all the required Microsoft stuff), yet when using Addon Spawner the DLCpacks scan fails every time, and when attempting to spawn by name with a trainer, it tells me it "Couldn't find model".
I'm trying to use the Delorean Mod, and the 50s Vehicle pack, which both seem to be working fine for everyone else.
I'm thinking it might be an issue with my firewall; I use McAfee and its blocked stuff from other games before, but simply disabling the firewall changes nothing.
Any help is greatly appreciated, thanks!
