Please help.

Hello
After installing the SimHub and running rFactor 2, when it finishes loading the track, it returns to the launcher screen, what could I do, thanks.
I tell you that I have the original game and also running the spotter (Crew Chief V4) active at the same time, I tried to run rFactor 2 without the SimHub and without the Crew Chief and now I can't run it either, after it loads the circuit it goes away to the Launcher window.
Please I need help because I can't use the game, Please, please.
