i have a computer with Windows xp that i had not used for several years ago in which i recorded several CD's with ATRAC3 format, days ago i started the computer again and i had to format and reinstall the Windows xp operating system with the original disk that came when i bought the computer, after installing all the necessary to use the computer again i installed sonic stage 4.3 now that i try to modify those CD's and save the music inside of those CD's, it tells me that it isn't the same computer, that i can only modify those CD's in the computer where they were created, but i am in the same computer. how can i solve this problem?
