My team builder doesn't load logos or models

Whenever I go onto the team builder site nothing loads correctly, If I go to preview a team nothing loads but text, than if I go to edit my own teams the logos will upload and show as my logo at the top, but it will not load in the logos part of the main page its just shows and EA logo or nothing, than if I go to make the unis it doesn't load the models. It also takes ages to save teams Ive made.
