I ran into the same problem recently and yes, you do need to get the latest
version of PKZIP.  What's happening is the latest version introduced a new
algorithm (imploding/exploding) which is an improvement over previous types,
but is also incompatible as well.  Try PKZ101.EXE - I got a copy from simtel20
the other day and it cured all problems.
