ILicenseAcquisitionHandler PlayReady internal service error

Hi,

I want to start the subscription sample from the PlayReady documentation.

When I want to test the server with the OTADLAClient.exe I receive this error in the event log:

Internal service error.\r\nClient record locator = 9f4a0520-33b3-49a4-96cc-24d33c29fafb \r\n\r\n Microsoft.Media.Drm.RMServerException: Unable to find any types which implement the interface \"ILicenseAcquisitionHandler\" within the specified handler assembly \"C:\Program Files\PlayReady Server SDK 3.0\vdir\bin\Subscription.dll\".

at Microsoft.Media.Drm.HandlerLoader.GetHandlerTypeFromAssembly(String interfaceName, String pluginPath)
at Microsoft.Media.Drm.HandlerLoader.GetLicenseAcquisitionHandler(String pluginPath)
at Microsoft.Media.Drm.LAHelper.AcquireLicense(XmlDocument challenge, String pluginPath, SoapUnknownHeader[] Headers, HttpContext context, PerfCounterRequestInfo& perfCounterRequestInfo)
at Microsoft.Media.Drm.RightsManager.AcquireLicense(XmlDocument challenge)

When I start OTADLAClient.exe I get a 0x8004C600 error code.

Can you help me?

Thanks in advance and kind regards,

Sven
