Can’t play online help pls

[nxckf]

I have been playing bikes for a while and want to race online but it seems no matter what I try I cannot join a server. It says data mismatch or bike mismatch everytime. Can anyone point me in the right direction? I think I have the newest OEM bikes pack but not sure because of this issue I'm having. Please help I just want to race online

Clear all your mods folders, including rider and tyres etc. (they can show a bike mismatch). Load just OEM from scratch, test.
