So using the system of AC, I downloaded the client to use it even on rFactor2 but it tells me that the login credentials are invalid.

I used the same as the AC App, any suggestions?

The client software for rF2, aut,obilista etc.. asks your username and email.
make sure you typed the email you used on registration
