I don't have the PowerPoint Importer, but you might run a few tests to see if the problem is with the importer add-on or with elements in your PowerPoint slide deck that is causing it.
I'd suggest creating a very short simple PowerPoint presentation (just a few slides with basic text and clipart images). Then attempt to import to CourseLab. If it works fine, there might be something in the specific PowerPoint presentation you have that is halting the import process. Maybe some fancy graphics, Smart Art or multi-media that is not recognized by the importer tool.
