Lenny's Simple Trainer, how to use it on campaing, and still play online later ? Hey there guys. So, sorry for this but, any tips ? I finished the game.. amazing btw.. And now i want to play with mods. And still, be able to play online.. If i try the Lenny's Simple Trainer, it can be removed in a easy way ? Or i have to reinstall the whole game if i do that ? And what about the Ban ? Rockstar seems too agressive about that.. I want to use the trainer on campaing.. And later, just go online. Without the trainer.. Should i disable connection to the internet and start in offline mode ? or this is not necessary.. what i can't do is click on "Free Roam" on Online menu.. ? Anyway, sorry my english, noob brazilian here. Steam version. Hope someone can help me here.
