We have wowza installed on Windows Server 2008 in Amazon cloud. Whenever we restart the windows service named **Wowza Streaming Engine 4.0.3** we get errors shown below and the live stream is not automatically started. The same setup on another server with **wowza 3.6.4** installed works fine.

Thanks for your help…
