I have an urgent problem.
I have been using Oxygene (currently 18.104.22.16841) and Hydra for several years.
In the meantime the subscription has expired for one or two years and I have renewed it occasionally. This has not been a problem so far.
This time the end of the subscription was on 23.06.2023 and I can now no longer open a project in VisualStudio 2019.
Does not matter.
Just read about the changed licensing policy since version 10 and renewed the subscription.
