Not sure what version of Zip you are using but I get an non supported version when I try to extract this on my server at Pingperfect.com. I can manually extract it at my home computer and upload the directory and files one by one using FTP but I thought I would tell you about this.
Which file cannot be extracted on the server, the PnB ZIP or the RWGui ZIP?
I can also compress it as a .7z, .tar.bz2, .tar.gz file (and a few other types). If your pingperfect.com server is on a Linux machine, .tar.gz is perhaps the most widely used in Linux enviros.
