Getting an error when trying to import .quiz file into Storyline

I try to import a .quiz file into storyline by following the steps  that I normally do when importing a power point (obviously selecting quiz maker ).  Perhaps I'm missing something but all of the slides show up i can select all and then the import process starts -  2 seconds later i get this error report.  I have tried and existing project that I am working on and also a blank project and I get the same error. :(  Any thoughts?
