Mine did exactly the same thing after I tightened it. I'll apologize in advance for not knowing all the technical terms for all of the parts in the door, but here goes:
You will need a flashlight and a metal coat hanger.
You'll have to roll the window all the way down, then move the interior rubber edge by gently pulling toward the interior of the vehicle and out of the way. Once you can see down in the door frame from the top, use your flashlight to look down toward the back of the vehicle.
When you move the door handle, look in the door and see where the motion stops. There is a metal piece that is supposed to be lifted when the handle is pulled, but the part it lifts will have slipped under it. Essentially you need to bend and work your coat hanger down under that and pull up. The door will open immediately.
I'm attaching a photo, but the area is so tight I had trouble getting a good one. Keep in mind, once you have it open, this will not fix the problem. This will allow you to open the door so that you can remove the panel and loosen what you tightened with Oki's fix. I got over zealous with my tightening and the same thing happened to me. Getting the door open is the hard part, but while it took me hours to figure it out, hopefully this will give you a good starting point.
