Error when running a Chemsep column

[Pepepepote1]

Hello,

I am trying to run a distillation column for my Air Separation Unit by using the Chemsep Column. After designing it and adjusting its properties I run it in the ChemSep window that pops up and it runs and gives me the right results. However, when I run the flowsheet in DWSim an error pops up.

This what the error says:
This error was raised during the calculation of a Unit Operation or Material Stream.

System.InvalidCastException: Unable to cast COM object of type 'System.__ComObject' to interface type 'CapeOpen.ICapeUnit'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{678C0998-0100-11D2-A67D-00105A42887F}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

Thank you
