Hi,
FYI this has not helped me. I'm still getting these errors, even after I did this and deleted the Zclass and all instances of it. Perhaps you're overwritting your Data.fs file with the old one instead of exporting all your contents through the manage interface. I tried both approaches and the first one, which seems to be easier, didn't work for me. So I tried the second one and it worked in my test server.
Unfortunatelly I'm on vacations now and I haven't updated my current production server; however, my test server uses real data. As soon as I can, I'll update my server and I'll tell you if I have the same problem.
