Looks like your site was completely removed from their index - that's not good!
(how do you tell? if a google search for site:yoursitename.tld returns no results !)
I don't have time to look at it closely, but you may want to fix your HTML validation errors. When was the last time googlebot visited your site, and did it deep-crawl or not? Were there any errors shown for your sitemap submission? It is a pretty "thin" affiliate site - wouldn't hurt to add more original content either.
