hey, i just got a 5510, but cannot for the life of me get my songs onto it. when i plug it in, the software doesnt pick it up, i cant find drivers for it, the manual says u just install the software and plug the phone in!

i can view it as a removable drive, but wen i drag .mp3 onto it the phone doesnt recongise it, because the software converts the songs into .lse???

any help appreciated.!
