Hey

I hope this is the right section to post my problem...

Basically, a client wanted some changes made, so I downloaded their Umbraco site to make their changes.
This is my first time ever working with Umbraco, so please bear with me if this is a simple issue, but your assistance would be greatly appreciated.

The download went great, the site worked perfect on my local machine and I was able to do what I needed to without problem.
Now I want to upload the site to our test server, so the client can see the site and see the changes and all of that...
I had some troubles with the upload (files timing out, etc...), so I think a file has gotten corrupted, but I don't know which it is... or if I'm even right in thinking that this is the problem.

Here's the error screen I get when I try run the site at the moment...
