I used the trainer again yesterday, it works absolutely fine, and I am not banned.
@hawks01lax, that is how I do this:
I start the Trainer, I start FH3, I pull the LAN cable to be offline (you could deactivate the network adapter as well, but I go offline physically), I use the Trainer (credits, wheeslpins, skillpoints), I close the Trainer, I close FH3.
Then I start FH3 again, THEN I reconnect online.
Since I started using this again recently, in the last week, I can confirm the above works and hasn't gotten me banned, I would add that deactivating the network adapter is also a good idea if you ever use your wifi, so pul the plug on your LAN, disable wifi, don't be stupid about using it, like adding 999,999,999 cash and going around the auction house buying everything in site, and you should be fine.
Not sure how to add credits or XP as im following the instructions exactly as they were given to me and it doesn't change. Am i missing anything here.
Read entire thread. Doesn't work later in the game. Use wheelspins option instead.
