[Zope] Importing a zexp?

[Jean Jordaan]

Hi all

When I unzip 
  KnowledgeKit-1.6.7.zexp and
  ZDP-Tools-0.1.zexp

into the import/ directory under the zope directory, and I try to 
import them (from http://jean:8080/manage_importExportForm ), I get 
respectively 
  "The object KnowledgeKit does not support this operation"
and
  "The object DocumentFolderProduct does not support this operation" 

Anyone know what's wrong?

Thanks!
