Aaron, which one step you have problem with (line #)?
I have installed this application and tried to run your initial script (except line 2 which refers to your local folder) and it works until line 14 where I can see this object doesn’t really presented (however I believe it is because I have no previous session to restore).
I created very basic script for this application – can you please try to run it.
Can I also ask you to record your manual test steps with Recorder and upload somewhere to see how it works on your side?
Regards.
