Jersey Editor problem

[Daneee]

Hi, I'm new to the forums so please forgive me if I post it in the wrong place. I'm trying to replace the Knicks home uniform with my self-made Harlem Globetrotters uniform. My problem is that when I replace a texture in Jersey Editor (64-bit version) my texture looks very distorted. I'm using Adobe Photoshop CS5. I've tried importing the images in bmp and dds formats but the results just don't seem to differ. I attached an image which shows how it looks like. I hope someone can help me.
