If more users are working on a network license, it is possible that not all modules or editions are always available. It could also be that you are working with an edition in which certain modules are not available (e.g. the concept edition doesn't contain modules for plastic analysis, dynamics,...).
The following message will appear:
It means that in the project some functionalities (dynamics, seismic, support nonlinearity, beam local nonlinearity, stability, mobile loads, plastic hinges, prestressing,...) are used that are not available with the current license set.
You could continue with reduced functionality, though it is advised first to activate all necessary modules or editions.
