I updated my theme manager and now I can't apply any new theme I download. I have re-installed this program 3 times and when I select a new theme--take GAMP's "Heaven" for example--I see the preview, click 'apply' and the next window I see is totally empty. No theme parts of any kind. I hit 'apply' again and I get a window telling me I must select a theme or skin. What am I doing wrong?
