That Feeling When Your Video Gets Corrupted

Sooo, I had a TF2 gameplay/life update video in the works that is months overdue, and decided to finally finish it today. I've been trying to edit it for the past few minutes, and Windows Movie Maker was acting finnicky, deleting entire parts of the video instead of trimming them, etc. Then, it crashed twice. Then the third time it crashed, I tried reopening the editor with the video. It said it couldn't be edited because it was corrupted. So I had to do everything over from scratch, and I almost got grounded because Mom thought my punching the wall in rage was me throwing my 90 dollar headset.
I am the luckiest person in the world for the original gameplay recordings to still be saved in my Team Fortress 2 folder. If I had deleted them in my recent desktop cleanup, I would've had to record it all from scratch again.
