Do you not have a copy of your past tax returns? Since 2007 just about every accountant I have used has emailed me a copy of my return. If you don't, you need to work on getting them and keeping them. Put them in a cloud account like OneDrive (which is free) or DropBox. Recouping your passive losses is extremely important and you have to be able to justify them as well.
Perhaps it is time to stop calling and emailing your accountant and make a drive to his office......and them find a new one. I personally use US Tax Shield.
