There is a technical discussion/ introduction to the EDX interface here Using EDX in QlikView 11 - basic example
This will provide you with an EXE file that you can run, often on your server, or even on your PC, to trigger a QMC task.
Note that the Active Directory account executing this utllity has to have the appropriate privilege to do so. They have to be a member of the "QlikView EDX" local group on the server that hosts the QMS.
The error you are experiencing "This Qlikview doc was created by another Personal Edition User" is because the user execution your script and calling qv.exe does not have QlikView licensed to that user or the document you are trying to open was created by a user that does not have their qv.exe licensed.
EDX does not call qv.exe but the document that EDX is trying to refresh must be created by a licensed user.
I read both of those, but cannot make sense of it. I found this: Trigger QV Task using command line arguments , which I think helped explain how to step by step set this up. Our JAMS guy was able to understand the code to execute it task we want reloaded, so I'm hoping when we get the EDX file saved on the server box, we should be good to go
