TypeError: fileList[i].split is not a function

I can drop the component onto an object on the stage but when I open the panel to add a transition I get this error:

TypeError: fileList[i].split is not a function

followed by a note telling me there is a minor update that I must download. The cycle then begins again.

Is there something more I need to do to complete the installation other than installing the .mxp?
