Not sure exactly why, I was able to crawl your site but here a few things that could be affecting , and will be affecting your rankings.
not sure whey you would have your robots text in the new directory http://www.deprevencion.com/new/robots.txt 
and why you would want to block access to all the folders you have blocked either. Unless there is a really good reason to do so, you should let every thing be crawled.
Your domain http://www.deprevencion.com 301’s to http://www.deprevencion.com/new then to http://www.deprevencion.com/new/
You should not have linked 301’s, each 301 will leak some link juice and Bing will only pass link juice thought one.

If I type in a rubbish address like http://www.deprevencion.com/new/fasfasdfafsd
i get a 200 response, meaning found, but there is not such page, it should return a 404, the page I am sent to has a image that is missing, that does return a 404, now first of all the 404 page should return a 404 not a 200, or its what is called a soft 404, you may see these errors in GWMT, bt if it did return a 404 you would cause a loop as there is a missing, that will cause another 404 to the 404 page with the missing image again and again.

There are 1,348 redirects within your site, you should have no redirects on internall pages at all, as you have the power to point them to the final destination, all redirects leak link juice, so why have them when it is un-necessary.

You have many canonical problems, one in particular is your internal links point to http://www.deprevencion.com/new/index.php , this means that you link juice is never returned to your true home page.

Bing API gives a loop error
The URL 'deprevencion.com/new/index.php' has been crawled more than 500 times. This usually indicates an infinite loop in redirection logic.

This would be because you home page has broken image links, that then get sent to your 404 page that also has a 404 missing image

Altogether, the redirections are a mess, I am afraid to say, you don’t need any redirects at all, so the questions is why have them?

OK after all that, I would say that you have a loop, that that rogerBot(seomoz) wont crawl

We did have an issue where some campaigns were only getting one page crawled. Alan gives some good advice here. I'd also email help@seomoz.org and ask them to take a look.
