Great. So, nothing is wrong with your machine. Did you download the updates of Growl and DiscCover, or did them come on disks? If you downloaded, perhaps you'd have better luck with new downloads. Perhaps there is something in the web site's FAQ. Now, I do not know what more to suggest, except to check with experts on the G-List at lowendmac.com .
