I began downloading the 10GB Xcode and iOS SDK when I left for school this morning. Why the hell iTunes would create an issue with this download is beyond me, but apparently having it running in the background was a bad thing. When I came back to the computer the installer appears frozen with About 6 minutes remaining. Even though I closed iTunes the Installer window is stuck open, the Running package scripts... progress bar is still glowing, but not moving. It's been 20 minutes and nothing has changed. What do I do? One big question I have is, what happens to the 10GB of space if I force quit the program? It's probably 97% compete. What happens to all that data that I started to install?? Hopefully someone out there can help me. It's greatly appreciated.
