itunes

[2ularbell]

I have just changed computers and moved my i tunes from one to another however the new computer has downloaded a newer version of itunes and now when I go to play a tune it states it cannot find the music so It asks do you want to locate it. you have to then go to the i tunes library and find the song before it will play - I have 3500 songs at moment and it would take me forever to do this one by one is there any way i can do the whole library at once???
