Computer problems

My 2 year old did something to my computer earlier today and it isn't working right now. I am running a computer checkup and I hope that I can fix it. I hope what I am writing shows up. My email is locking up so I can't write to people. I can't upload more yarn pictures because it looks like Demi deleted them. I am going to take some new pictures and keep my fingers crossed that I can fix the computer mess up! She wasn't out of my site for more than 2 minutes. I have no idea what she did. If nobody hears from me in the next few days it will be because of whatever she did. LOL! I hope to be back online soon!
