Sounds to me like you didn't start your server properly. You need to specify the -c option, like this: run.bat -c jbpm. If you are using the starter's kit, I'm under the impression that it comes with a start script (for Windows at least) that will do that for you.
Yeah I've been using the startup script all along. I just reinstalled and was able to modify the default simple process and deploy it. Either I had something corrupted, or my first basic process wasn't so basic and I had created an error in the XML. Thanks for your response. Much appreciated.
