http://www.info-zip.org/pub/infozip/FAQ.html says:

   ... in August 2001, PKWARE released PKZIP 4.50 with support for large
   files and archives via a pair of new header types, "PK\x06\x06" and
   "PK\x06\x07". So far these headers are undocumented, but most of their
   fields are fairly obvious. We don't yet know when Zip and UnZip will
   support this extension to the format.

Looks like both your unzipping programs can't handle these new file
types. You should find that p7zip (which is in extras: yum install p7zip)
works for you. Otherwise you should find that
http://nct.digitalriver.com/fulfill/0018.032 (where you can get a 30-day
trial for the official port of PKZip) gets you out of this particular
tight spot.

Hope this helps,

James.
