i can't upload screenshots

I just don't get it. I can't upload nds game screenshots to this website anymore. Whereas, before, I can easily do this. After downloading 80+ screenshots for them, now when I do this they would say "Registered Users" only. What do they mean by this. Do I have to buy Premium to be a Registered User. After giving them 80+ screenshots for some of their NDS games that doesn't even have screenshots now I'm not welcome to upload anymore screenshots for them! What an ingrate!

Try logging out, clear cookies, cache etc. and then log back in.

the 'registered user' message just means it can't tell you're logged in for some reason.
