Hello people! Good evening, I'm hopeless and I have a serious problem with my OS X 10.8.2 Mountain Lion on my Mac mini. I downloaded the OSX 10.8.2 Combo Update packaged and the Pacifist for testing how I did for my Macbook White. When I extracted the App Store from Pacifist, the App Store from my Mac mini has been replaced. After the finished work, I noticed the weird icon of App Store, it became one application icon and not anymore app store icon. I open it, it crashed quickly and gave a report. I copied the original App Store from Lion to Applications, but the Applications didn't allow because it's used and required by Mac. I tried to open the original Mac App Store from Lion in my own OS X Mountain Lion. What will I do?
