I did what the url suggested but still have the same issue. What should i do next?

so you have set all the protected mode off.

Yes. I think problem starts with IE does not work on my computer. I keep getting error message saying internet explorer has stopped working. If I log into my window with my account, ie gives me error but if i log in under my bf's account, i dont get this error. Do you have any idea why?

then create a new account in control panel>>user accounts.
