Feeding Weather Underground Successfully

My HP ProBook is now feeding Weather Underground with data from my AcuRite weather station. AcuRite customer service provided the solution.

Getting a new Weather Underground Station ID solved the problem. Why? I don't know, but it worked.

Feeding Weather Underground

I own an AcuRite personal weather station (PWS) that has performed flawlessly. I run AcuRite PC Connect software on my MacBook Pro to feed my PWS data to Weather Underground via. USB connection between the PWS and the Mac.

About two-thirds of the time, I use the Mac away from the PWS, so the Mac is disconnected from the PWS and no data is fed to Weather Underground. I wanted to feed Weather Underground 24/7, so I shopped around for a computer that I could dedicate full time to that task. 

I purchased a refurbished HP ProBook 640-G1 14-inch Windows 10 laptop and it arrived here yesterday. I downloaded the Windows version of PC Connect, configured it the same as the Mac version, but I cannot get it to feed Weather Underground. The software is working OK otherwise, but nothing I tried gets it to feed Weather Underground. 

I am very frustrated. I plan to contact AcuRite customer support next week when they return from vacation. In the meantime, does anyone have any ideas about what could be wrong?
