Why is the downlaod 950 MB and does it contain the security patach SS204NW files or will this patch have to be reapplied after the service pack is installed. Will the service pack install replaced the IDM3.01 Imanger NPM back to default like NW65SP6 did ? and ruined my Imanager tool for IDM3.01. I am now on IDM3.5 and the only way to managent it is from iManager.
