I am using SD-Jukebox for the first time and find it the most frustrating piece of software I have ever used

I'm wondering if anyone else has experienced problems with this program? (Version 2.4 as supplied with the SZ-CB7 Kit)
Example : I compiled 8 MP3s from Audio files on my PC, following the procedures in Alec's book. Having completed the procedures, the files played OK in my KN7000. However, when I tried to add another MP3 to the existing Playlist, using the same procedures, at the end of the 'Check-Out' process, the Microsoft 'Apology' Error window appeared asking if I wished to report the error to MS (which I declined) and the program terminated. Strangely enough, when I placed the SD Card in my KN7000, the added MP3 file played perfectly!!
Example 2 : If I try to rename the Playlist (Not the Default one) using the 'Settings'
facility in the 'List' window, no matter what name I enter in the 'Playlist' name window, I am told that it is an 'Illegal Input' and to 'Enter between 1 and 30 characters'. Even the original playlist name is rejected !! Renaming and changing the order of the MP3s in the 'List' window works OK
Example 3 : In the 'Settings' window, there is an option to set the 'Mute Time' to any value between 1 and 10 seconds. No matter what value I set in this window, for the selected Playlist and click on 'Apply' and then 'OK', when the MP3 files are played in my KN7000, the interval between the track is always about 1 second. I need the interval to be 8 seconds for my specific application.
I could go on about more bugs in this program...........
I tried the program with the same MP3 files on two different PCs and the results are just the same.
I really need a solution to the 'Mute Time' problem since I am in the process of compiling a set of MP3s for use in my KN7000, for a theatrical production this coming Wednesday.
Can anyone help? Are you there Alec ?
