My Avatar isn't changing.

[oscarreadwin]

When I first joined MCSG and its forums, my skin was Dipsy, the green teletubby from the TV show. I soon changed the skin and have since made my own.
Every time I try to change my avatar to something else, it comes up as the cursed teletubby and I don't know what to do. When I delete the avatar, it goes away. But if I try to add a new one, it turns into that green monster.
Any help? Does my avatar appear as the Teletubby or is it just my computer?

Thanks
