i know this has been asked a million times before but my searches arent coming up with anything

iv rescanned my new tracks with mixmeister but they have already been imported into serato and i cant get it to read the bpm i then tried to redo the id3 tags with mp3 tag tools but i cant remember do you go copy 1.1------>1.2 or 1.2----->1.1 if you guys get what i mean,

i know there was a thread with i think nik39 explaining how to do it but i cant find it

secondly i also cannot get itunes to read the new bpms and deleteing and reimporting does not work either

i have only started using itunees recently to organise my stuff and it works great except i cant get the new bpms to show any help greatly appreciated
