for those who cannot patch version 6028,
go to ftp://nprotect.maplesea.com/audisea_patch/patch_files/
then find AUDITION06058.zip , download it.
after downloading, extract all files and replace your old files in the audition folder.
after that, (only for XP users, i don't know about vista.)
Start>Run>type regedit>HKEY_CURRENT_USER>Software>AUDITION>ASIA_SING.
you should see 4 files there.
right click on the VERSION, then modify.
change it to decimal, and change the value on the left to 6058.
there, you should be able to play now :D
