So my friend recently updated his graphics card from a Gigabyte something or other (I think 650 but I'm not entirely sure, it was old) to an Nvidia 1660. When he tried to play a game of NBA 2k14, however, he noticed that all of his save game files, as well as his mods were gone and nowhere to be found. I am the one who changed the graphics card for him, but I didn't touch his storage devices at all, so I'm quite confused as to what happened to his files. Has anyone ever heard of this happening? I'm assuming the files are gone forever, but is there anyway to get them back?
