Here's another try at getting this question addressed.... I have 2 Zope installs. On the newer one (2.2.1) when I try to import KM Net News (to install in the products list) I get the following error. Note I previously deleted KM Net News (the earlier version) but think that Zope might have gotten killed right in the middle of the delete and not completely deleted the product. Is there any way to get rid of the Class ID KMYear that does not show up in any way through the interface?
