CDMage: File Length Doesn't Match Sector Boundary

[Chilla_Chinkilla]

Hi!
So I looked at the tutorial on how to edit Final Fantasy Tactics, I have all the programs needed and the FFT WotL ISO on me, but when I try to mount it into CDMage using M2/2352 track, I get an error saying "File Length Doesn't Match Sector Boundary" and then it just won't mount.
What does this mean exactly? And can someone help me out? I'm a total noob to this and I want to learn how to mod this game really badly since it was always a fave of mine, so sorry for my ignorance.

For WotL you use UMDGen, not CDMage
