so my iTunes library and media was stored on an external drive that i accessed wirelessly thru and Airport Extreme.

all of a sudden iTunes no longer reads that library. iTunes has updated and now i can't seem to redirect it back to that volume.

have tried internet suggestions of deleting the latest library file and replacing with a previous auto-back up one. didn't work.

is there a way i can relink it without copying all the media into a new spot again?

thanks for any help offered.
