Help! - Making Textures

[GoingDigital]

I've just started using BrawlBox, and I could use some help. I'm currently running BrawlBox vo.63d, but when I try to preview my texture (note, this is the texture, not the shadow), all I get is a white screen, and one more click, *WHAM* Not responding.

Also, I'm not stupid, I know how to edit a picture, and to export a .png out, edit, then replace.

After I've changed what I wanted, I saved it as a .pcs, as well as a .pac file.

I put both files in the correct folder (private>wii>app>RSBE>pf>fighter>kirby), and named it Fit<Character>0X,
but when I try to use it in-game, (Brawl Minus v1.0), I get the default costume. Can anyone help? I'm dying here.

Thanks,
