I don't know where you play at, but if you play on FTP, you should check this out before you select a program to use.
Poker crusher isn't allowed by their site. By the sounds of what your holdem genius program does...it would be prohibited by FTP as well because it calculates pot odds
and percentages. (section 1 under 'not permitted during play')
has a similar webpage, but i'm not familar with it since i don't play there often.
I personally use poker tracker 3 which is allowed by the sites, so you won't have any problems. Its definitely on the 'upper end' of the complexity scale but its basic functions aren't all that hard..and for the price compared to others...your getting alot more functionality.
Since you've gone out and published this publicly now...i'd 'really' suggest making sure that 'holdem genius' is allowed by the site your on. I'd venture to guess its not...in which case you should stop using it immediately before someone who's read your post decides to burn you just for the hell of it.
