Presenter 10 publishing error.

Please Help! I'm getting the error that Presenter 10 cannot publish a presentation and to check if I have enough disk space and permissions.( which I do) I have tried everything... different profile,different computer, uninstalling, cleaning temp folder etc, etc.One clue is, other presentations are publishing, except this one, and it is slightly larger than the rest however, even when I try cutting it up and reducing the size( even under different names) it still will not publish. Any Ideas?
