Hi
Thank you for posting this on the forum,
Our apologies for all of the problems you have encountered. We just deployed a new release of Insight and it should resolve some of the account access issues. I want to recommend you post these kinds of questions on the Insight 360 forum, the chances of you finding answers are also bigger if you search there - take a look at this forum thread similar to yours:
In case you have any questions let me know,
Best Regards,
