Have there been any conflicts between NIS 2009 and Acronis True Image?

I recently installed Acronis True Image Home 2009 for cloning and backup/recovery.  Acronis freezes up before backups are complete.  I've tried all I know to do with Acronis.  I disable antivirus, live update and idle scanning while I'm trying to run the backup jobs.  Does anyone know of conflicts between the two programs?
