Single step animation error: Error HRESULT E_FAIL has been returned from a call to a COM component.

Hi,

I have a problem with construction of Discover .ARC file: in the Materials Studio manual it is written "You can create all of these files, except the .his file, using a text editor, such as WordPad on Windows or vi on Linux", so I assume that converting a trajectory into .ARC format should be possible. However, when I try to open and animate the file in the attachement, I get the following error:

Single step animation error: Error HRESULT E_FAIL has been returned from a call to a COM component.

The corresponding .CAR and .MDF files where constructed in Materials Studio, then the .car file was used as a template to insert unwrapped coordinates from another simulation run. I have checked if the problem persist with .ARC trajectories from Discover, but everything works smoothly. What is wrong in this setup?

Best,

Vitalie
