Plug Ins, Exclamation Point, Crashing Project... help please (Logic Pro X)

I recently bought Logic Pro X on the new Macbook Pro 13 inch and one of the songs I made is unable to open properly. Unless I disable the core audio, I can't even open the project. If I do disable the core audio, then I can open the project but no music plays. All the plug ins and instruments have exclamation points on them. I have tried importing the project using the All Browser feature but I could not get it to work. I've shut down my computer multiple times.
