Two suggestions. First would be to change over from the no longer supported Dynazip and use http://www.sweetpotatosoftware.com/SPSBlog/PermaLink,guid,b5fdd81c-4d47-469b-acbb-ddda807adacc.aspx

Craig Boyd ZIP stuff works great.

Dynazip has a test switch that will check the integrity of the zip file. However, you might find it easier to use Craig Boyd's program. It will do the same thing in a much simpler way. And yes, it will read zip files created by Dynazip. They all use the same standards.
