How to use the trainer?

Hey guys,
i just installed FiveReborn and downloaded and installed the server for it. But i cannot figure out how to get the Enhanced Reborn Trainer to work. I put the .asi file in the servers plugins folder and the config.xml in the root directory but if i try to use the Trainer in-game nothing happens.

Put enhanced reborn in your CLIENTSIDE plugins folder.
Put the confix.xml in your GTA V root directory.

Open with F1.
