You can try
PC Inspector File Recovery which is free. (Norton costs money of course.) If you delete items via the Library in LW, they by-pass the recycle bin. But their skeletons will still be on the hard disk drive (HDD.) But to recover them you must stop using any program that writes to the HDD. Likewise if you downld pc recovery you should downld & save it to another computer. And to recover files, try to recover to an external device or another partition where your erased files were not stored. But sometimes recovery programs like norton can't recover files until after the comp has rebooted or on a different day. Just my 2 cents. You can hope it's not as bad as Fabion suggested.
