Hi, as far as I know, the lifetime subscription is allocated to your user ID x not a Trainz version. I bought mine as a stand alone…
Maybe check with N3V?

Trainz Plus is separate from your lifetime fct. You also shold have been getting a $2 or so deduction from the price of Trainz Plus as you already have a non expiring FCT
