Of all the products I've purchased, it seems like only these three products can't be downloaded right now.(Problems that were accidentally discovered today. In April to May, I installed these three products in the game after I bought them.)
We're currently experiencing server request/activation issues. Product activations will temporarily fail. We apologize for any inconvenience as we work towards resolving these issues. Last Update: 06/14/2024 18:00CT
With the work schedule these guys keep, They are actual railroad employees, it may take a few days for them to get back to you.
