Hello, Andrei

I'm working using the orhelper, but I had to format my notebook and the library is not working for me anymore... I get this error:

:25:17.545 [main] INFO n.s.o.s.providers.TranslatorProvider - Using default locale en_US 23:25:17.561 [main] INFO n.s.o.s.providers.TranslatorProvider - Set up translation for locale en_US, debug.currentFile=messages.properties 23:25:17.569 [DatabaseLoadingThread] INFO n.s.o.d.ComponentPresetDatabaseLoader - Loading component presets from datafiles/presets Exception while calling OpenRocket Traceback (most recent call last): File "Simulation.java", line 336, in net.sf.openrocket.document.Simulation.simulate File "BasicEventSimulationEngine.java", line 73, in net.sf.openrocket.simulation.BasicEventSimulationEngine.simulate Exception: Java Exception

The above exception was the direct cause of the following exception:

The above exception was the direct cause of the following exception:

Process finished with exit code 1

What problem do you think can it be?

Thanks in advance!

In case someone has this issue in the future. Please add the cause and solution here. Thanks.

The problem was caused by the lack of the motor added on the OpenRocket system.

I was struggling with that until I found out my motor wasn't already added to the software thrust curves. So I went to Edit > Preferences, and added the .eng file to the "User-defined thrust curves"
