I received an error message while extracting the file with WobZip
Thanks for sharing your problem with us, there could be two possible reasons for this first is unsupported method and second is bad zip header in the archive. Ask the person that has created this zip file to use good zip software. You can use winzip to extract the files. Just download the trial and use for 30 days. You can download the winzip from here http://www.winzip.com/win/en/.
I hope this will solve your problem.
