when in the marketplace to update packs you own, they wont update

Ever since Minecraft was put in the launcher, I have had issues getting into the marketplace. It will either not let me in no matter how many times I click on the button or I can get in and no updates will show they are complete after I update them.  My skin on my guy doesn't always show up either... at times it will show up as default Steve or the female one without my gamertag.
