trouble adding sprite

[Cube]

I downloaded harlan's WWII mod to try to add more tanks to med mod 2. I renamed the sprites gu200-gu216, and changed the sprite tank file from 38 to 200, and got a message saying gu00.spr not found. I came here to the forum and found you can't use numbers greater than 200, so I renamed them to less than 200, and replaced sprite tank from 38 to 103 expecting to get it to work, but it still gives me the gu00.spr not found error. Am i doing something wrong?

Very strange
Spelling error in MM2_newsprite.txt possibly?
