I'm not sure what you mean by "if adobe analytics still works?", Adobe is still probably the leading Web Analytics software out there... (despite Google Analytics being free, to coin a friend, GA is more of a Web Reporting Tool... AA is an actual Analytics tool).
I assume you have purchased a plan with Adobe, your CSM should be able to help get you started with all the access you will need.
If you have access and need a place to start, @FrederikWerner's "Implementing Adobe Analytics in under 10 mins" is a great introduction to the basics. https://www.youtube.com/watch?v=VRi3WdwkA3g
Without knowing where you are in the process, I am unsure where to start helping you...
Do you have specific questions that we can answer?
