Hello, exactly this happened to me too today.
My administrator didn't move the website but when I start to connect my Contribute CS4 it asks me at the very end if I want to remove the administrative settings, etc.
But I am not sure what to do, as well my Administrator not either.
It works on other PCs, but not on the new one.
Did you find out a solution meanwhile for that?
Sorry to border, but I am in Tokyo and almost nobody can help me here!
This happens because you have moved to site to new host, the host name and the IP address will differ from the one saved in the cthubxxxxx.csi file inside _mm folder in the site. Or the IP address is not static and got changed.
Solution 1: Click Yes (All the adminitrative settings will be removed). And Administer the site again, create new roles and configure the role settings accordingly.
Solution 2: If you have access to the server, Open the cthubxxxxx.csi file inside _mm folder of your site and replace the old hostname and IP address with newer one. Then reconnect.
Hope this solves your problem.
I didn't move my site to a new host, it just wrote it and I don't know why.
In my case I asked for a setup key from the administrator which I used
when I set up contribute.
I clicked on the attachment from my administrator with the key and the
rest was done by itself and I was again connected.
Hope this helps...
