First of all, thanks for help to other forum users !
Unfortunately, today is my last day of subscription and I`m not sure if I'll be able to renew it in the next few weeks. So I guess I could not be able to help you even more.
Well, i don't know your specific situation, but i would like to emphasize than you can continue using RailClone after of the subscription period.
All our licenses are perpetual, and the subscription just lets you to receive updates and new versions of the sofware. You can find more details in our FAQ
In fact, to avoid confusions, we replaced the term "subcription" in our documentation by "maintenance plan", which is more exact.
