Hi, Luis.

> I have downloaded the tier-Adapter 2.21, but i want to know where can i find articles to help me in the use of this tool in the UT Magazine or in other place

Notice the support group (bilingual in Spanish and English) is now located at:
http://groups.google.com/group/tieradapter/

The articles can be found in UT Mag at this link:
http://www.utmag.com/ViewPageArticle.aspx?Session=466268744B6A36756836383D204F6B3769756B5672436452496B654265674651526D773D3D

To go on with the complete series you can just use the "More from this author" dropdown at the top of the page or the table at the bottom of the article. Also, you can read the series in English, Spanish or Portuguese by using the link at the top.

Hope this helps,
