ok, i have easy cd creator 5 platinum with the latest upgrade and i burn my mp3's onto a disk. i first burned a session making sure not to finalize the disk only finalize the session, it burned and worked in my mp3 player. after it burned it asked me to save the project file so i did just in case. then later i got more mp3's and so i decided that since i still had plenty of space that i would put them onto the same disk that i had done before. i double click on the saved file and it opened up easy cd creator and i added the files to the list. i already had 11 songs on the cd and when i added the other songs onto the disk it came out to be 23 files. i burned it and when i played it in my mp3 player it didnt find the other songs, it found the originals butnot the newly added ones! i opened the disk up on my comp and it found all the files!!! WHAT IS WRONG!! P.S. i have XP on my computer my mp3 player is a Diamond Rio SP50
