Well after long looking for a solution I found a way to import the project, first unzipped the project in the netbeansProjects folder, and went to open project option, and selected the folder is the project was "Successfully imported!"
Well thanks to everyone who tried to help me so far.
Probably because the zip is not compatible with the netbeans project format, or is not a project created for netbeans.
