This morning, I pressed "Update All" as the App Store was prompting me to update a few apps. Unfortunately, I had to power down to leave before the updates were completed. When I powered up my computer at school, one of my apps - iAnnotate - had a dark icon and was unresponsive. I went to the App Store and hit "Update All" again, but it finished the other app updates. My iAnnotate icon had disappeared then, so I went to the "Purchased" section of the App Store and it indicated that iAnnotate was still on my computer. I hit "Open," but nothing happened. I even did the general search on my computer and nothing came up when I typed "iAnnotate." The final step was to check my iCloud back-up settings in the Settings App, which still indicates that iAnnotate is being backed up. As a relative newbie to the Apple world, I'm hoping there is some trick to get iAnnotate to re-appear on my computer. Unfortunately, I have a HUGE test tomorrow and all of my notes are organized on that program. Can anyone help?! Thank you in advance! P.S. I also tried to power down and back up, but still no iAnnotate.
