Hi, I wondered if anyone could help me on this issue that is driving me nuts. I'm new to zope, and google has been fruitless on this. I have installed Zope 2.7, Plone 2.0.5, and have Python 2.4 on. Not supported, I know, but I needed 2.4 for something else, so figured I'd try it. Anyway, I have it all up and running fine, but some Products won't install. E.g. SimpleBlog, CMFBoard, and ArchExample. Well, okay, they will install, and zope will start, but they all have the same symptoms. Whenever I add a blog, forum, or article from them, I get a KeyError, on field 'zid'. With ArchExample, it actually says "I can't find this file", but I know it means the same error (I hope). I've also tried creating my own class in ArgoUML, ArchGenXML'ing it, and I get the same with that too. Even if I create the simplest of classes. Wha could be wrong here? Give me hints and I'll dig deeper, it's just that I can't find anything on google at all :-/ Thanks, Jamie
