Championship Skin codes question please help!

Quick question.. so I went to Worlds in Korea and got my Championship skin code but when I entered it into the site i accidentally typed in my email instead of my username. So i did it again using the same code and my username but i'm not sure if it will go through or not because on the site it warned that if you use the wrong username it won't work and if you use a repeat code it won't work. Also it says it takes a couple weeks to register but the code expires in like 3 days so I can't even check to make sure if I got the skins or not.

Please help!

Thanks
