System comprises MSI K9A2 Platinum MoBo and AMD Phenom processor, 4gig Geill Ram, 2x Western Digital 400 gig HDs and xfx 9600 GTS with 512 meg graphics. DVD is Sony NEC Optiarc AD 7200 dual layer 20x SATA. I purchased Powerpack 2008 in February, but it would not recognise the Graphics card so could only get vga type graphics. Some time in June (not at home machine so cant check) I bought Spring edition which I downloaded as an iso (64 bit version). Copied this to DVD and installed it successfully first time. I cannot remember whether I did a clean install or not. Every couple of weeks or so I check for updates and select all to be downloaded - even though I have no idea what most are about. Last attempt to download gave an error message when trying to install the packages and that is where I remain for the moment.
