MacAmp Lite X Question

[F. Hill]

The June 2004 issue of MacWorld has a terrific section called "Digital 
Music Superguide".  Among other suggestions and tips, it notifies 
readers that the audio player MacAmp Lite X has been discontinued and 
is now available for free, with registration codes included.  It is 
recommended because it can play music formats which iTunes cannot play. 
  The MacAmp Lite X download is still available at:  
<find.macworld.com/0004>.  I downloaded it, along with the registration 
codes.    Unfortunately, when the application is opened to the "enter 
registration" section, the registration codes cannot be entered.  The 
blank lines will not activate to receive the code numbers.

The website for MacAmp Lite X appears to no longer exist.  
VersionTracker no longer even lists MacAmp Lite X.  There is no 
discussion on this in the MacWorld forums.  Has anyone downloaded 
MacAmp Lite and successfully entered the registration codes?
