Hi there!
My friend lost his e-mail because he forgot to log out from school computers. The e-mail was on the truckers mp account and he even forgot his password.
The problem is that he can't create another truckersmp account with that steam ID, because it return an error which tell him that the Steam id is associated to another account.
What he should do? Has a lots of DLCs bought on this acc.
He can even demonstrate that he's the official owner of the steam account.
