Hello, Not sure if this is the right place but... I just got my MBP back from service and was getting everything set up. Apple replaced just about everything! While I was checking and installing updates, a program, iMovie was listed, and when I tried to update the program I got the message saying... I checked my system serial number and confirmed I was logged in using the only ID I have. My other purchases are listed. I also checked similar threads and saw someone had a problem like this because iPhoto was now called Photo, in my case iMovie hasn't changed names. Any ideas? Thanks.
