I have found some info on thier website regarding a different issue "If you get an "Error 5:" message when autodelete runs, then you most probably are a Windows Vista user and have UAC (User Account Control) turned on. The only way to run autodelete with UAC on is by running it as an administrator. You can also right-click on the autodelete shortcut and go to the 'advanced' tab, then the 'advanced' button and activate 'run as administrator'. The program will not give an error but you will get a UAC warning every time the program runs. I have not found a way to avoid this, so the only advice I can give is to disable UAC by going to the control panel and in the search type 'disable UAC', you will be given a link to disable UAC." but i just saw your post saying that u have tryed administrator mode.
