Skin Glitch

I don't have the updates on the login screen its just all white. When I logged in about a week ago only a few skins where Steve and Alex then this week my skin and everyone else's skin was Steve or Alex. I reset Minecraft, my computer, uninstalled and reinstalled Minecraft, I hit the repair button and after all that nothing changes back.

I would really like my skin to show up and I would like to see other peoples skins too. Please help.
