All duplicated files deleted

hello guys! I was using the free version of the ccleaner and it was doing good, until I used the option to delete duplicate files, the cleaner sad that it was quite much duplicated files, so I deleted those files and I left just one file in my computer, after that almost any file and app that I had disappear. please I need those files and apps. can anyone help me please. other than that the program is awesome, and I thinking to upgrade to pro version

Based on the lack of support, I’d advise against paying for the upgrade.
