Poker Academy Pro vs the Standard version

What is the difference between the two versions of Poker Academy? To be honest I'm just getting started with online poker and have not actually deposited any money before. I'd prefer to purchase the standard version because it's cheaper, but if the standard version is complete crap, I may just do the deal they have at poker source online to hopefully save some money. I know you guys probably get a lot of questions like this so I'll just appologize in advance. But seriously, thanks in advance for any input that you give.

To help you out, here is what I want to accomplish.
1. Not be a looser at poker
2. It's still just for fun (no WSOP dreams)
3. Understand odds better
4. Read my enemy's hands better

I've been lurking around for a while, and have learned a pretty good deal from the forum, but I'm looking for a more hands on education. (Sorry for the horrible first post, I don't mean to be begging for help already.)
