Having an issue with project not saving as a zip file

I get an error stating I can’t save the zip to the intended file. I try to alter the location even to my desk top  and nothing is working.

Blue box appears upon publish, functions like a link or a pop out.

How do I get rid of this blue pop out box that appears only after I am publishing? What is it’s purpose? Where do I go to remove it? 

PROJECT PREVIEW ERROR

When my projects are almost ready, I choose preview project and I keep getting a buffering error with this URL: local host… and it just continues to buffer. It worked before. Is this a computer setting or a file corruption?
