When going to Noesis->Settings and hitting "Reimport All" and some errors occur in loading any of the XAML files, the Reimport All XAMLs popup just hangs in mid-progress and never closes.

Is this happening with an empty project with Noesis package you have modified?
Or is with your whole project? If that is the case, as said in the other post, it would help us a lot to identify all the problems you are having to have access to the project.

Sorry for the inconveniences.
