So I installed Liberty and the Revo Remix theme, and some other stuff, and it was working great for a day, and then all of a sudden my Marketplace just stopped working. The vending app is still there, but Marketplace doesn't show up in my app drawer, in my installed apps list, or anywhere. I still have my shortcut on my home screen, but clicking it doesnt do anything. Tried reinstalling it by copy/pasting the vending.apk from a fresh version of Liberty into system/app on the defunct Liberty, and nothing. Even tried doing it via an update.zip install. I really don't want to do a complete reinstall. Any help?
