I have been using NOD for about 8 months and have been very impressed with it. Good job to the developers. I have just reciently been experiencing a problem with the updates. The download seems to work just fine but I get the following error when it applies the update. Error occured while updating program components (Cannot replace the current file) I've seen several different errors that I have been able to resolve the cause. This one is a complete mystery. I suspect that de-installing and reinstalling is a possiblilty but I would prefer to do that as the absolute last resort. Reason being is that I don't want to have to re-install on about 40 other PC's that are having the same problem.
