Stopes working after update

I updated it and it stopped working right. It freezes when I go on to some ones profile to look at their art, and when I try to add my art and go into "category" and I pick the category stuff. It will just sit there not loading. So I cant upload my art unless I put category, but category wont WORK!!!!!
