That's a SHV error which can be caused by an outdated game (ENT is trying to use a native or feature which is only present in newer game versions) or a mod conflict.
Which part of the config? Tested it and keybinds etc all work fine.
Does the error happen on load or when your save loads?
All the vehicles are in ENT including the ramp buggy - in fact ENT dynamically makes the vehicle lists now so if you don't have the correct DLC installed, it won't appear (because your game doesn't know it exists). Make sure your game is up to date.
You can narrow down what is causing it by removing all other mods APART from ENT and loading GTA. It's likely SHV.NET is causing an issue as some users had similar issues before with mods conflicting with each other.
Not that I know of. That's a known bug R* should have fixed a while ago but haven't for some reason as it happens Online where this station is "officially" meant to be.
If you go to: %appdata%\GTAV Enhanced Native Trainer and rename ENT.db that usually fixes crashes on startup BUT it resets all options etc.
At the moment you can't due to issues with users using the source to make menus for Online. I was working on a basic translation support system but had to pause due to lack of time.
Vehicle names and vehicle mods are localised - just option text isn't.
You can disable it under Misc.
Is your game up to date? Works fine for me on 3 different PCs.
@Slash_Alex would be the best person to ask about that as he developed that option.
At the moment ENT supports both due to the controller overhaul. It's a sort of "side effect" of removing Xinput and using GTA's input system.
Off the top of my head the translucency has always been in ENT. It's not something a user can disable or change I'm afraid.
Make sure your game is up to date as the names are extracted from GTA's memory. If you use a cracked copy for example this won't work.
The vehicle previews are also loaded from GTA's files (and the ent_previews.ytd file).
Can you try JUST loading ENT (no other mods) and see if the game still crashes? That'll help narrow down whether ENT is causing this or another mod is conflicting with it.
Make sure dinput8.dll is alongside the ScriptHookV.dll file. Dinput8.dll injects the ASI files, the scripthook allows them to function.
I believe that should be in there but I also remember we were having issues with some interiors which used a lot of props crashing the game when you attempted to teleport there (the Nightclub was notorious for this) and this may have been 1 of them.
You'd want to bind all the keys to -1. I was working on disabling the controller but had to pause it due to lack of time.
