I got a new theme called Classy Corners Dark Today L 4.5 (it is a pretty sweet theme all problems aside. it converted me to today style). When I first loaded it, the problem was that the there wasn't a MEdia Net (browser) icon. Instead it was just a blank space. I can still roll my selector over it, its just that nothing is there. And the icons aren't customizable so I can't just switch it out. Is there a way to switch it? Currently I'm using the Red Hot today theme, but would like to switch.

Have you tried deleting it from your phone and re-downloading the theme?

yup

Then I would notify the website/builder of the theme...Maybe they can fix it and send you a new link for it.
