Error: ExternalInterface/CalcExternalInterfaceFMUImport: Error when trying to initialize

edit

Hi, i'm having trouble with coupling Contam to EnergyPlus. I've been using the step by step guideline in the Contam user guide by NIST. I've created the ContamFMU files, a IDF file from the Contam3Dexport tool and Contam resart file. When i try to run a EnergyPlus simulation with the IDF file from Contam i get this error:

* Severe * ExternalInterface/CalcExternalInterfaceFMUImport: Error when trying to initialize
* ~~~ * instance "ContamFMU" of FMU "ContamFMU.fmu"
* ~~~ * Error Code = "3"
* Fatal * ExternalInterface/StopExternalInterfaceIfError: Error in ExternalInterface: Check EnergyPlus *.err file.

Has anyone had this problem once before? How can i fix this error? I'm currently using EnergyPlus 9.1.0 and Contam 3.2, I've also used Openstudio to edit the geometrie from the Contam IDF file.
