Downloaded and upgraded my macbook pro with no problems to OS X Lion however my iMac is having a problem. I've completed the download from the App Store 2 times and when the download finishes it tells me that there is an error and makes me restart the download.. Any tips or tricks of getting around this? I barely use my iMac, its basically only used to sync my iPhone at certain times and surf the web. Everything on it is basically factory besides flip4mac and a few apps downloaded from the app store.
