Custom profile header Problem

Hello!

I've wanted to Upload a Profile Custom Header, to get My Profile look better and Stuff, I've even Made a Header EXACTLY 1200 Large 270 Height (Pixels).

When i' had uploaded it , it brought me back to the Profile Screen (Where should be the Header.) Saying that the change was done, but the header Did not appear.

I've Checked the Size, The Image's format (Tried with JPG, PNG, GIF And Another)... But didn't work
I've Checked Changing the Browser from Chrome to opera!, Same resoult with Even INTERNET EXPLORER).
I've Tried re making the Image.. Nothing
Deleting the File and Re Uploading.. Nothing
F5... Nothing.
Deleting Coockies... Nothing
Asking 3 Mods.. Nothing.

Anyone can Help me?

Try resizing it to 600x135, and then re-uploading it (Don't resize the original image, make a copy of it, and resize that). I've had many problems in the past with AtWar not uploading images that are the exact maximum allowed, and usually adjusting the measurements to half of it's original size allows it to be uploaded. There's also the chance that it's simply large of a file (Which resizing would also fix). You also cleared.refreshed your cache, yes?

I dont think anyone can help you sorry :/
