I have just been working on a skin, and I really wanted to upload it. So I saved it, and uploaded the file, when I saved the file it said "Invalid Skin : Detected transparency in the body of the skin. This will show black in the game. Fix and reupload." I checked the file, there was no transparent bit apart from the outside (The part where you didn't have to use) And I tried uploading again, but it wouldn't let me. Any suggestions?
