Hi Kevin,
Just thought I'd mention that the windows Recycle Bin only usually works with files deleted from the Local Hard Drive (and specifically via the local Drive letter assigned to that drive usually C). Files deleted from Network Drives or even Drive letters mapped or substituted back to the local drive C are not usually placed in the recycle bin. Unfortunately it would seem that a restore from a backup is going to be your only option.
Good Luck !!! Our thoughts are with you...
Peter
