Well I didn't back up anything

Hence why I need a disk/file recovery program, possibly a free one. Cos it's all there, I just need something to recover it with. I made a new user and that one seems to be fine. But I just wanna get the deleted stuff back that's all.
And umm everytime I log in to my original user account, I get a temp profile, when I log off the temp profile it gets deleted and I get another one. Hence why my music got deleted cos I forgot to put it back into the folder that doesn't get deleted.. And yeah, I was making cds so I needed to have it on my desktop.
