SSRS 2008 R2 System.InvalidOperationException: Client found response content type of '', but expected 'text/xml'. The request failed with an empty response.

I have a custom program that calls and runs reports in SSRS 2005 I have upgraded to SSRS 2008. I changed the remote.config that that my program points to and directed to the new server. Now I can log into my new reports server and run any report do what i need but when I try to use the report server from my program  I get the following error

System.InvalidOperationException: Client found response content type of '', but expected 'text/xml'.

The request failed with an empty response.

   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)

I have Google this error and tried some different things with no luck. I am running this on MS Server 2008.

Does anyone know how to get this fixed?

Thanks!
