I'm not sure how I did it, but after deleting everything in 1881, and deleting the flow tab and making a new one. The thing finally work.

EDIT: for some reason, after restarting the Node-RED, the ui went blank again and it'll show up again if i delete and paste a new one and deploy it

EDIT: another thing I've tried is only entering `node-red -p 1881` and that actually work well, but I won't be able to see the flow if I try to look into the Context Data, so I believe the other cmd (`node-red -p 1881 -u c:/node-red-1881`) would allow me to view the flow in the Context Data. Just a curious thought, does the user logging into the Node-RED editor affect it?
