Hello, I have a PC with Windows OS 8 and I downloaded Openproj and the files are now in a zip folder. I can see all the files. When I select Extract and select desktop or a folder to put the files, I can see them. The problem is I don't know what to do with all the files. I tried clicking on each file to see if I could open so I can start (launch) to create a document but I'm not having any luck. Can someone give me some directions because I'm frustrated! Thanks
