scheduled quotes setup not working

I've having trouble scheduling the the quote updates using the instructions provided. I'm using Windows 10. I'm trying to get UpdatePSData.bat working first. It's in the PSDataExtract folder. When I run the task with start in argument provided, I get a task scheduler error "The directory name is invalid". If I remove the start in argument, I get last run result in scheduler of (0x1). So in trying to debug, I changed general task scheduler settings from run whether logged in or not to run only when user is logged on. That also gives me directory invalid error. But now if I keep that setting but remove the start in folder argument, the batch job actually runs now, but with just a bunch of failures trying to find the script files.

Any idea how to resolve this? It seems the start in argument is required, but I cannot get the batch job to run with it in place.
