Report Server Not Responding After Config Change

Firstly I should say my Reporting Services were working fine until I changed a setting in IIS today - under the Virtual Directory for the site I clicked Properties>ASP.NET>Edit Configuration. Changed 'Authentication' to Forms and everything went wrong; changing it back to Windows made no difference.

Now when trying to navigate to Report Server / Report Manager I get these errors:

RS : An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help Object reference not set to an instance of an object.
RM: The report server is not responding. Verify that the report server is running and can be accessed from this computer.

Following advice found elsewhere on the web, I checked my web.config file for an an erroneous xmlns entry... but it wasn't there. I have also deleted/recreated my virtual directories from within IIS/RSC. Also I have done a basic reinstall of Reporting Services (from within Add/Remove Programs>Change).

Below are my error logs and the listings for my web.config files; hopefully these will be of use in working out where the problem lies - I really need to get this fixed as soon as possible.

Thanks in advance,
Dan
