I have been trying to simulate this but it won't and it gives me those 2 errors
As @winny says in a comment, you need to fix the library problem first. 

Any errors after the first one cannot be trusted to be real. I recall file locations being a bit tricky in PSPice/Orcad simulations (the simulator is very good, however). 

This reference suggests that you must save the library in this location: C:\OrCAD\OrCAD_16.2\tools\PSpice\Library. (or whatever is the equivalent in your installation).
