Problem in PPT or Articulate: There was an error in accessing ^0

I'm getting this error message "There was an error in accessing ^0" after publishing a file.  The file is essentially trashed after that.

The only thing I can think that is causing this is the InvisToolBar button program.  I tried publishing a file with using InvisToolBar button, and there seems to be no problem.  Publishing a file with the InvisToolBar button active SOMETIMES causes the error.  Maybe there is a new version of the InvisToolBar button?

Does anyone have any ideas?  Has anyone experienced this error?

Thanks in advance.

Scott
