I signed up for the free TS2016 TSRewards gift when I purchased TS2016 on the same day it was released. I have not received any bonus DLC -- nada, nothing. I opened an email to DoveTail Games / Kayako Help Desk to complain. They asked me to resubmit my contact information which I did. Still no bonus content. Rats!!! I did get the EMD SD60 M upgrade that everybody else who purchased TS2016 got, incidentally which I purchased on my own previously -- but no bonus content. No Pump Car. No Joy! Everyone else, who I have read in this forum, recieved a secret code. And they got the prestigious DLC. But not me. I have received no secret code. The email did not get delivered into my spam folder either.
