Dear BD Aqua,
Hello again! Thank you for the tips. I will keep them in mind.
Actually, I was just frantically trying to delete my message, because after I submitted it, I continued trying to solve this problem and I did. By using Time Machine, I managed to restore the app, etc. I had tried it earlier, but I must have been missing something.
Thanks again. Your notes will come in handy in the future.
