We've been using Contribute in our school district for over five years.
Yesterday, out of the blue, we started getting reports from users about a
message that "Contribute could not read the shared setting file for this
website because the file has been corrupted. To re-create the shared setting
file, an administrator must administer the website again." When I tried to go
into Contribute to administer the site, it wouldn't let me connect.

With no other option, I deleted the connection, re-created it and had to reset
all of the roles. I spent the day re-creating the roles and just sent new keys
to the teachers to allow them to connect. I tested a few of the keys and they
seemed to work fine. However, when the teachers tried to use them, they got the
following message: "The connection key you are trying to import is corrupt,
please see an administrator for a valid connection key".

I'm at a loss at this point. I don't know why they wouldn't be able to connect
with the new keys I just created.

Our environment: A mix of Contribute 3.11 and Contribute 4 users (all Windows
platform). I administer the site using Contribute 4 but have kept it in
Transition Mode. We've been set up this way since the summer and had no
problems with it until yesterday.

As of right now, I have about 175 users that are unable to make changes to
their websites and with school starting just about a week ago, they are really
on me to solve this problem.

Thanks!
