Amazon web service requires signature (1 Viewer)

[justinteract]

Hi MP team,
not sure if you aware, but it seems that amazon requires users to sign requests send to their web service from now on.
I have noticed that the "search for cover art" in the music view does not work anymore. Looking in the debugger I have seen that the request "ItemSearchRequest" throws the exception

2009-08-25 17:38:47.275400 [Info.][MPMain]: Cover art grabber exception:System.Web.Services.Protocols.SoapException: The
 request must contain the parameter Signature.
   bei System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response
, Stream responseStream, Boolean asyncCall)
   bei System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)
   bei AWS.AWSECommerceService.ItemSearch(ItemSearch ItemSearch1) in M:\MediaPortalSource\Databases\Music\InternetLookup
s\AWSECommerceService.cs:Zeile 112.

This is what amazon says
We previously announced that by August 15, 2009, the Product Advertising API will require all requests to be authenticated using request signatures. Many of you have already implemented signed requests or are in the process of implementing it, and we thank you for your timely cooperation...

Sorry that I cant look deeper into this, but I will be on vacation from tomorrow on.
Hope this hint helped.

cheers
