Been trying to download FCPX to my new MacBook pro via the AppStore. I repeatedly get the message "Hash Mismatch" with the options cancel or retry. I have stuck at about 140MB into a 1.5GB download for hours. I have tried logging in and out of the store and even restarting the MBP. Nothing seems to fix the problem. Anyone had any experience with this error message? No posts came up via a search
