OC,

I tried

1. deleting the old notebook and creating a new one and selecting General Compute

2. I also deleted the existing instance and created a new one. After this i tried creating a SQL wearhouse

3. Whether I create a new instance or delete existing notebook the result is the same. 

4. From the other thread --"I experienced the same yesterday when I imported some of my notebooks. I noticed that this error only appeared for imported notebooks because the environment version was 1 by default. Changing the environment version to 2 solved the problem for me. Maybe this is the solution for your case too". -- This is not applicable to me as i did not import the notebook. Yet I tried selecting '4' in a newly created notebook. Its the same result even if I select 1, 2 or 3. This looks like something else. Request you to investigate. I really need to get this working. I am targeting at least 2 certifications by November
