Forza Street Lost PI Numbers on Top Cars Today

Is there a forum for Forza Street? I lost a large number of PI numbers today on several of my top cars and not sure who to contact to have that looked at. Any help is greatly appreciated. Play is on Windows 10 64bit installed on an ASUS G731GU laptop.
