Importing contacts csv

[HarryZyx]

I have a Basic account. I'm trying to import a personal contacts file. I've created a csv file using the format in the download sample. After I've selected the file, I click on Upload, and get this message "User not login." What does it mean?

I asked for help on the Chat line, and the answer there gave me a completely different csv format, so I also tried a new csv file in that format, but the result was the same.

What am I doing wrong?
