In order to see data you have to hit the funnel that is on the right-side on the top of the grid. No data will load until you hit this button:

Still not understanding what you mean by you cannot "create a new user in it"; are you trying to create a new admin user through the admin panel? Is there a specific error message that you're getting when you try this?
What controls specifically have you found are not working in Chrome? I use Chrome regularly and haven't had any issues with the admin panel. The same goes for others on our team that use Chrome exclusively.
