I get the following error when trying to deploy a Page/Template/docType (anything!) using Courier 2 Express.

This instance is running v6.2.1. I have a v6.1.6 instance that is running a near identical configuration and that is working as expected.

There error is as follows:

error:System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> Could not find the default database provider, please ensure you have all the required DLL's in /bin, and that courier loaded successfully. To debug, turn on debugmode in /config/courier.confg, and examine the /app_data/courier/logs error log files at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at Umbraco.Courier.RepositoryProviders.CourierWebserviceRepositoryProvider.OpenSession(String sessionKey) at Umbraco.Courier.Core.Packaging.RevisionPackaging.Package() at Umbraco.Courier.Core.TaskManager.manageTask(IRevisionTask value) 6/4/2014 10:20:02 AM

I looked at the error logs and they gave me no additional information.

I searched around and could only find reference to nightly releases with no fix. I compared the /bin to our working v6.1.6 version and all the courier dlls are present and accounted for. I verified the courier.config to make sure the repositories were well formed.

Any ideas?
