I tet to extract carsetups and this comes up all the time so I cant edit the tunes :
The last time I saw this error it was due to a title update that increased the security on Forza save games.
Was there a recent update to the game?
Edit: if I remember correctly a fix was released for Horizon for it soon after so it may be a case of the developers needed to update the tool to bypass the updated security.
it does it on everyone i do exept one save
So it works on all other saves except this one?
Upload your save to mega.co.nz and I’ll have a look at it for you and see if I get the same error.
only one old one works
Go to http://www.mega.co.nz
Upload the save that doesn’t work there and I will try for you.
