To use it click on the Home button [top right hand corner] > Log in > User Panel > Log in > Below the list of characters you have it will say;

Below that click on "Choose File" > Feralheart folder > Presets [NOT MY_PRESETS] > Double click on the preset you want to be uploaded [Ex. D-ead7Dog_5.fhp] > Click "Upload Preset". :)
