Help! My computer shut of while I was trying to save my PN Key File

I am trying to finish my very first app. I went to save the PN key file and my computer shut off. I went to Certificates, Identifiers, and profiles and it says that I have reached the maximum allowed. I dont know what to do. I cant do anything with my app this is so stupid how could they make it so something like this was even possible. I am totally screwed. Please help me!

Can you clarify what “PN key file” means?
