Extracting to "C:\Documents and Settings\Michael Howard\Local Settings\Temp\"
Use Path: yes Overlay Files: yes
Error in file #1: bad Zip file offset (Error local header signature not found): disk #1 offset: 0



That is the error I get when trying to extract the file. What exactly is wrong with my file here and is it fixable?

Looks like it's corrupted...if it's just the header that's missing, you might be able to fix it, although I would just get it again.
