Thanks for the response!
That was the first thing I tried but for some reason I am unable to turn off restricted mode on youtube. The settings show up when I click on my account but I am unable to move it to the 'off' option. It says it is on and no amount of clicking can drag it to the off button. When I scroll down to the bottom of the youtube page to try and turn it off, the option to click the 'no' box doesn't even appear. This is a private computer and I am the administrator so there is no reason why I shouldn't be able to turn it off my account, but I am unable to.
