When I tried to do a Visual Recognition test, I needed to create a Watson

Visual Recognition Instance. At my Visual Recognition screen, there is no existing

 service instance, so I tried to create a new one. This was impossible, a message like

"You can only have one instance of a Lite plan per service. To create a new instance, either delete your existing Lite plan instance or select a paid plan."

Now there are several questions:

• How to delete exiting instance?
• My notebooks which I have created for the second lesson will be still working ?
• Are these instances interchangeable?
• How to solve the problem when an instance is provided to you right after you login and on lesson one on your course at Coursera start with a visual recognition sample. In fact this visualization sample has been added after I already finished 75% of the first lesson. I noticed when I came back to end.

PS:     I will not buy another plan, not at least with my actual knowledge Maybe later…
