How to get sunroof back on track?

What is your question?

The sunroof worked perfectly before but while it was open one night it got shoved back from someone standing out of it and it sounded like it got knocked off track. Now the motor works because it will open and close, but now when you first open it, it doesn't pop up as high as it was and it makes a popping sound when it first opens then needs help closing or it will try and reopen itself halfway closing.
