I just purchased and activated and uploaded my first document and am hitting a wall already. The system says that my document name isn't valid. I've edited it a number of times but can't get the system to go anywhere. Can you help? I'm on mac. I just need to add signature and initial blocks.

I haven't done anything w/ this app yet except uploading 1 document and it said I only get 3 signatures and that one is gone already so I'm really confused about this as well. Thanks.
