Cant access Category List in Moving Pictures (1 Viewer)

[conguero23]

When I try to get into the list of categories you can only see the list and are unable to focus on the buttons to choose a category. This just started a couple of hours ago. I tried re installing MP as well as switching different skins with the same issue. All the other moving picture menus work except that one. Any help will be appreciated. Below see the error that I am getting when trying to enter the category menu.
