Welcome to the Dataiku Community. We are glad to have you here. Sorry to hear about your problem.
From your description below I don't think I can solve your problem. I use Data Science Studio (DSS) on my Macintosh and on Linux Cloud Instances. However, there are lots of bright folks in this community I suspect someone can help.
I'm wondering if you can share a more detailed error message may be a screenshot. That level of detail and context is often helpful. You also might put in a support ticket to see if you can get the issue resolved in that way.
