Upgrade required to create new notes???

[victorcamacho 0]

Hello, 

I am not sure if this is a joke or some kind of technical problem, but I cannot create any new note without upgrading. I still have half of my space to upload images and so on. 

Any one any idea?

Many thanks

What's the error message? 

What's the client? 

Can you explain it better?
