I understand that troubleshooting can be frustrating, but you’re not providing us much information to help you to ease the pain 
So, do you have a C:\openhab2\addons folder? It happens to me regularly that I accidentally move a folder when navigating with the Windows Explorer. I’m wondering if the same has happened here and it is now at some other location.
Did you do what Rich asked you to do: Clear the Cache and then delete/rename the log files, and restart OH?
Can you post the contents of the ipconfig /all command? I think the mysterious ip address may be the ip address from your Wifi network (or your fixed network and the other one from the wifi) now that we know that you’re using a laptop (which is fine, it comes with a free UPS in case of powerloss 
).
Can you ping hp27? Are you running a local DNS or did you add this to your windows hosts file? If not, can you replace hp27 with the IP address of the device you are trying to control?
