I have a Creative Zen X-Fi and up to now have used Creative Centrale, the software supplied with it. I have had a number of problems witht this software in the past, and I gather that it is generally regarded as not very good and best avoided. However, I have managed to use it for about a year, although it's been a struggle at times. But then just yesterday, after I had been using it to edit music files on the Zen, it suddenly refused to recognise any of the files, and has continued to do so despite my re-setting the Zen several times and re-installing the software.
In view of Creative Centrale's bad reputation I decided to try something else, and someone on another forum recommended using MP3Tag for editing tags on the Zen. I have tried this, but when I try to access files on the Zen I get messages saying "Filename not valid".
I should be grateful for any advice. I should point out that my technical knowledge is fairly limited so it would be helpful if any advice is given in simple language!
