Are you 100% sure the damage isn't from an irrecoverable source? (In my case it was from Psionic Blast)
Are you 100% sure you are running the correct copy of the game? (assuming you have multiple folders that have different versions?)
Are you 100% sure overwriting the file was successful? (compare the dates, maybe something prevented deleting the old file)
