Sitemap-XML and robots.txt issue

Hi all!
First post here…
I started using wordpress to create a website for my business (a Law firm) in august after my “wordpress mentor” suggested me it would be far more efficient than Dreamweaver.

I’ve just finished building today but I’m having problems with google. It appears that my site is preventing search engines from indexing it. However,”prevent search engines from indexing this site” is unchecked.
After submitting my sitemap url using google webmaster’s tools
(/sitemap.xml, created using XML-Sitemap plugin) I am told that my robots.txt file is preventing indexation.
My site URL is http://mobaabogados.com/ (it’s in spanish but you’ll get the idea)

And that’s that, I’m stuck.
Any help would be greatly appreciated.

Kind regards,

A.
