Program error

When trying to create a report from one of my applications i get the error below. I strongly suspect that this might be Comodo related. This is a Windows XP workstation running CES. Can anyone point me.on a scale of 1 to 10 my computer prowess is about a 7. Thank You Jerry

Are the applications running sandboxed? Do the D+ logs give a clue here?
