Trouble with ripping using asset studio

[RavenclawNimbus]

So, I'm trying to rip from a game, but when I extract the files they sometimes have errors so some files are missing. Note that I'm ripping the dlc sprites from the game, and that I'm using asset studio. There might be a problem with ripping the dlc, and the version of asset studio I'm using might be too old now. I got it around last year.
