Okay, so I was just using Photoshop and then my friend wanted me to try and airdrop it to her since she didn't have photoshop. I tried to airdrop it to her and it failed. Later on, my photopshop icon had an question mark on it and i realized that it won't open. I started to play around and accidentally uninstalled it by going to Applications->Utilities->Adobe Installers and clicked on Adobe Creative Suite 6 Master Collection. After uninstalling it, I thought I could reinstall it again but I can't find any files or whatsoever to install it again.
