Very worrying issue with a Windows 8 user account

Hi, everybody! Today, I ran into this worrying issue. I went to load up Jetpack Joyride and I got this error saying that the app could not sign in to my Outlook account. I quit the app and then I got this error from Windows saying that it could not sign in to my Outlook account. I don't know my password. I sign in via a PIN, so I forgot my password. Should I reset my password on my Outlook account and then reset the password on my computer, or when I reset the password on my Outlook account, will it sync with the account on my laptop? Should I do anything else? Will this work? Should I restart? Please help. Thanks.
