I asked you this question as I had faced the same issue when I had installed the SAP CM module in my environment. But I didnot uninstall and reinstall the agent.Please do a debug for your agent server and try to check the error in the proclog. In my case I was getting a error in proclog with extractor management. This was happening as Extractor Management was check though it was not getting used. Just did donot detect for Spawned, Intercepted and Extracted jobs and it worked fine.Not sure if this will help you.
