You said you tried all of these things in the original post, but I think you want one of these products to Zap you like celestial lightening in the first try, and you're suddenly Captain Suave, otherwise you deem the product as worthless. (excuse the exaggeration - now that you're irritated by this, and perked up, read carefully).
The principles that David DeAngelo can't fail if you actually read what he's talking about, and just 'get it' about women. Don't put so much pressure on yourself to be 'one of those guys' who can walk up to an attractive woman right from the get-go. You're making a 'rule' for yourself ( Tony Robbins in Awaken the Giant), that if you can't do 'this' successfully now, than your challenge is 'this or that' and that it's a monumental challenge requiring much conquering of yourself.
Drop that personal rule that you're holding for yourself.

The xtrememind free version of MLF has you visualize with your five senses. I'll bet you are just playing it in the background wanting it to do the work all by itself?? I listen to their products with the attitude that the subliminals and other technology are just the bonus, and I take the visualization very, very seriously. This is what has been producing results for me lately.
Putting yourself in the situation in your imagination, with Feeling, over and over again, and imagining yourself having fun with them, a'la DeAngelo-style, is where the real magic and progress happens.
Neville (someone quoted him at the XtremeMind forum, go read it) says that it's important to imagine in your mind, from your point of view, the reaction of the woman's face to this powerful new behaviour of yours. Imagine another person's reaction to you, and this creates a new version of you, that would have to exist, for that other person to react this way. Read Neville's Power of Awareness for more on this.
The reason why I bought the commercial version of MFL myself, was because the free version tipped me off that the commercial version would have extended visualization of imagining (Neville-style) the reaction of the woman, to my new behavior.. finally.. a product that would guide me through applying the principles in Neville's books that I"ve had on my bookshelf for 6 years. I didn't have enough discipline or trust in myself, to just do it myself, without the help of the CD, but that's ok..,I'm glad someone created a product such as theirs (and I plan on getting LSC's IPM).
Anyway, do the work BOTH, with the club you're involved in, AND on your own in your meditation/visualization sessions in a disciplined and super-regular, committed times.
Do it all.. but allow your subconscious to take these changes on its own time.
Be gentle with yourself.
But I do like your style of putting yourself out there. But take advantage of that experience, and in your meditation time, look back at those real-life rejections (or whatever) and analyze what was running through your mind at those exact times, and examine the outdatedg beliefs that you were holding to cause you to handle yourself in the way you did, etc..
Don't look at my suggestion of 'meditating on beliefs' as some weak esoteric, vague attempt at sounding spiritual in this post, and all.
Mike Pilinski, in his ebook: "Without Embarassment:The Social Coward's Totally Fearless Seduction System." clarifies the importance of daily silence and examining the 'stream of beliefs' that run through your mind regarding women.
