Can you compare the corrupted save file size to the size of a working previously saved file? Hopefully not to far back in the storyline? Then you at least get an idea of much data was lost and if it is worth the effort to try and salvage it. There may be so much missing data that the game can not even begin to load enough information to tell you that it is corrupt. Other than that there is no other help that I can suggest.
You're an idiot. 'Inactive' doesn't mean everyone should go around being an ass because nobody's gunna notice. If anything, someone turns up and goes 'oh tits, brilliant, that would've been great when I was 13'
