Blitz, are you referring to the digital download at this link:
http://www.starrynight.com/digital_download.html ? The digital download is of the most basic of the versions available, The Enthusiast. If you bought the CD version, there shouldn't be any difference with the features at all (though some trial downloads have a habit of locking out some features, leaving you to spend the money to find out what the fuss is all about!)
When I bought my pack, it came with extra DVD's but many of the features were still the same as the trial version I downloaded. But since the trial version I downloaded yonks ago was also of their most basic software, the enthusiast, obviously then there are more functions and features on my CD compared to the version I downloaded. Does this make any sense? I hope I've answered your question!
Ken, that horrible noise, is that coming from you or the computer?

Seriously though, where is the noise and how bad is it? I'm glad your computer didn't freeze yet. Looks like that might have solved your problem

Fingers crossed!
