The method or operation is not implemented - when loading a presentation with a chart

Greetings,


I’m getting an exception “The method or operation is not implemented” creating a Presentation instance from either of the PPTX files attached to this post.
Ideally I’de like to find a way to load this presentation as it is, but if that’s not possible on a short-term, I would appreciate some help in identifying what element is not supported, so I could change or remove it.

I’m using Slides for .NET version 14.4.0.0.
