GTA 5 Won't Start!

[Digital16]

I installed the NVR mod, VisualIV, L.A Vegetation and of course ScriptHook and Simple Trainer and it worked fine, then I followed directions verbatim to add a vehicle and now GTA 5 won't load. If i delete the game and do a clean install the game works fine. It's just when I add the mods it won't work... Any suggestions please? The game is from RG.
