If you want to change a specific hotkey in the trainer you can change it in the Hotkey Manager under settings,
just click on the option and enter your new hotkey inside the window.
If you want to load your own custom header:
Download OpenIV (if you don`t already have it) navigate to RampageFiles/Textures and open Textures.ytd.
Now you can replace the texture "header_custom" with your own (512x128) also don`t change the name.
Log files are stored in RampageFiles/Logs if you have any issues you may want to look into these files.
