when you download a program, sometimes it can change your "default search engine" Ex: google, yahoo, etc... and you can not access things you need. So here is what you do to change it back to the original default search engine
1. Open a new tab on google chrome. click on the three lines by the address bar that I circled in red:
2. go to settings
3. scroll to the bottom and hit "show advanced settings"
4. scroll to the bottom of the advanced settings.
5. click "reset browser settings"
6. a confirmation will pop up. hit "reset"
