What version were you using before? Must be a very old one?
The way you phrase your post, and the fact that you chose the 'General Discussion' board to me signals you mainly wanted to ventilate and share some frustration.
Which is perfectly fine and understandable of course.
If you are interested in using and learning the current version, it would be good to isolate the separate challenges, and do a search for answers for each of them.
If you can't find answers, you can always ask on the Questions board.
Else it's probably better to return to the old version?
