user14698: Premiere Pro is not allowing any objects (I have tried titles, video and audio) to the timeline. When I drag it over, it comes up with a closed hand with a crossed circle. I already have media, but now I can't add any more. No layers are locked. I haven't changed any options. Help? Me and my teacher could not figure it out.

user8000: Where premiere allows you to drop or insert clip depends on on Source patching and Track targeting. Basically, you can only drop clips into a track that has Source patching turned on in the track header.
You also cannot drop clips onto tracks that are Locked
