Benvenuto su GTA5-Mods.com

Hey guys, I'm new to using mods (other than ones from Steam workshop). After watching some YouTube tutorials about using some of these, I decided to give it a try. I downloaded this charger model, renamed it to "Buffalo2" and dragged it into OpenIV to replace the existing Buffalo2 files. Now when I try to start my game, it says there is a corrupt file, so clearly I messed up somewhere. I was hoping someone would be kind enough to give me some advice.
