I havn't played my copy (steam) since around February and when I loaded up... Nothing! And in the saves directory.... Nothing! No files, zip. I have played for 53 hours is there any way of recovering these files? A google search rendered little help about save files disappearing altogether. Please, any tips (a miracle would be nice) are greatly appreciated!!

Same problem here. I think it may have to do with the hacking incident. They should be in your steam/userdata/[usernumber]/[patchnumber]/remote. Hasn't worked for me, just got a new computer, but the saves should synchronize with steam.

Same problem here, but got it fixed. Go to My Documents/My Games/FalloutNV/saves. If nothing is there, check a previous version of windows and see if they are there.
