Best Chess software advice

Hi, I am looking for a chess-software that I will buy, download and install on my computer (Windows 8.2).
I do not know much about chess-software, so I need some advice.

I use to have, Chessmaster Grand Editon, but due to damage on the DVD, it is not working anymore. Therefore I need a new software that is easy to use. It should also suggest best move and calulate chance of winning/remis/loosing during the game.
I do not need the best of the best, as I am merely a club-player and I also got Houdini 4 chess-engine, which I perhaps could use with my new bought chess software.

So what do I buy?

If you don't mind to spend money Aquarium + Houdini 4 for playing and Chessbase for working with databases.

Nevertheless you can save money by using free Arena GUI with stockfish engine

Does Fritz have a coach-function, that suggest what line to play next? a blunder warning? ability to calculate which side got the better winner changes...and so on? (Chessmaster does)
