Error to start a simulation

Good afternoon,

I´m following the example exercise on the "Getting Started_Tutorial" manual by DHI and when I arrive to the Dynamic Simulation Experiment chapter (Chapter 7 on the guide) I constantly get an error when starting both the steady state and dynamic simulation (attached below).

What do I need to change?

Thank you!

This looks more like "just" a Warning message, not a true Error message, and your simulation should start - with true errors, the simulation would not start at all.
Is this the case? And do you get meaningful results, or not?
It is difficult to exactly say what may have happened. If the error persists, please contact Support (mike@dhigroup.com) and include the actual logbook (save as text / xls file).
