[Zope] Unpckleable error

[Vicente Castelló Ferrer]

Hi all,

I have updated  my zope 2.4.0 installation to a zope 2.4.3.

Everythong seems to work, until i try to add a zcatalog, a squishdot product
or a zdiscussion product, where i get Unpickeable error messages or object
is not callable (on the squishdot).

Do I have to re-install these products?

if yes ... How do I re-install Zcatalog???

Thanks in advance
