Winrar has a good zip repairing ability, try the trial out to see if it will repair the Zip.

Your problem may not be as much that the file is corrupt, as with its size.  There are two versions of ZIP format -- the classic uses 32-bit sizes and offsets in its directory structure, so you really can't have a file larger than 4GB.  A version of the format using 64-bit integers (and effectively having no limits) has been around for a while, but may still not be supported by all software.

The first thing I'd do in your situation is try a couple different unzip tools, starting with the same one used to create the archive...  If you are trying repair utilities, make sure you do it on a copy of the archive, because a repair utility that only understands 32-bit ZIP format would probably only do additional damage.
