Jo, you should shoot me an email at throwaway127@gmail.com
There is a $35 piece of hardware on Amazon I will point you to that I use for my small computer business to fairly easily recover "unrecoverable" files.
Loads of sympathy here. Two weeks ago the HDD on my gaming desktop crashed. Took the weekend with a Mircosoft tech who didn't want to give up before we said "He's dead Jim".
New SSD and 2 HDD's will be here soon, mean while I'm getting re-antiquated with this console gaming thing.
Still a great game nevertheless, I'm just pointing the irony of Valve's system where the fans do almost everything (New weapons, stats, skin, maps, modes) and they still don't add! You got Paladins who probably doesn't have a fourth of Valve's money, and they add a new hero monthly. XD
...and weapon skins!
Seriously though, Valve abandoned TF2 already. Now it's all about CS and it's golden child Dota. It's funny because the community it's still very active. There's a s***ton of workshop weapons and maps, but Valve can't be bothered to add it...
