Cannot execute solution

Hello,

I am new to this solver and trying to follow the tutorial video on Altair Flux YouTube channel.

The video name is: Vibro acoustic coupling to LMS Virtual Lab.

I have reached the last part where the solver shows me an error, where it cannot execute solving of Forced Computaation.

The message is as follows:

evaluateInstances : Execution failed.
Failed execution
Failed to create a new instance of Force computation.
Can not execute the following command :
lastInstance = SurfaceForcesComputation(Name='ForcesComputation',
                         Interval=EvolutivePath(parameterSet=[SetParameterXVariable(paramEvol=VariationParameter['ANGPOS_ROTOR'],
                                                                                    limitMin=9.54,
                                                                                    limitMax=10.0)]),
                         ComputeHarmonics='NoHarmonics',
                         ComputationSupport=ForcesSupport['FORCESCOMPSUPPORT'])

Please help me what to perfrom next?
