    You will need to redownload it from the App store. Start the App Store app and click the purchases tab while holding the option key. This will allow you to click download next to Lion and save the DMG to your drive. Do not start the install once the download finishes or it will erase the DMG. Then use this free utility to make your USB key installer.
