TS Flashbackup Help Needed Please

Hi Guys,

I have been trying to make a full backup of my DM800se using TS FlashBackup.  I was able to successfully make a back up using TS Flash Backup but now i can't anymore.  Even when i flash the previous backup to my box and then try to create a new backup straight away, it doesn't work for some reason.  I have attached the log file.  Any help would be great appreciated, have been wrecking my head for days with this.
