First of all make sure your file is opened, a easy way to do this would by clicking the “Save” button after you open your file, if it saves… it is, and still if the button is enabled, can you upload your save for me so I can have a look?
But try it this way… (I’m guessing your loading it from your USB using Horizon)
Drag your file from your USB / HDD from Horizon onto your desktop, then open the file from there.
Yeah, I would like to know how to add more than one set or at least more than one of the same car. I’m a huge Supra fan and I want more than one Top Secret Supra but even if i click add all then change cars i don’t want into something I do want it wont change in the game.
The cars should show up in the garage if you add a new Row at the bottom of the Garage GridView, even if you have multiple. Before it wasn’t supported, but there was an update for that. If you are having problems with this, please send me your ForzaProfile and I will look at it.
