"Story load error: loading file 'savegames\sdsd\story.000'."
It looks like the story file from your old save has become corrupt. Try making a copy of your old save game folder, delete the story.000 file in that new folder and replace it with one from a new game. If the copy loads, that will confirm the file story.000 was corrupt.
Unfortunately, the two story.* files keep track of quests, so can not simply be replaced with files from another save without causing problems with various quests and/or cutscenes, etc.
If you burned the old save directly to CD-R/DVD-R as a backup, make sure the files in the save folder are not marked as read-only, as that will also cause the game to crash trying to load it.
Did you just keep the latest save from your old game? How far were you in the game?
If you still have your old PC, does the save load there? Maybe the story file got corrupt transferring it over, and might be ok if you zip the save folder and try again.
