Is Blender using CPU? Do you have the most recent version of the tools?

Check Task Manager and see if Blender is using CPU. If it is, then you just need to be patient.

It sounds like an up axis is incorrect somewhere, possibly you are importing an animation made with one model in SFM onto a different model in Blender.

It's a check box in the list of installed Blender add-ons.

It looks like another script within Blender has messed with the console window, and replaced a key component with its own "StdoutOverride". Try disabling other add-ons until the problem goes away.

This is a Blender issue. Nothing an add-on can do about it.

The file is broken. Both meshes have data for four joints, but only two joints exist.

Pupils are rendered entirely by a shader. They don't exist on the model, you just tell the shader where the eyeball is.
