Who/How to contact

The recent newsletter I got is busted. None of the links in this newsletter works. Here is an example of a link,http://ct.techrepublic.com.com/clicks?t=43078446-1ae117fa44855d48a4606c9d313949c1-bf&brand=TECHREPUBLIC&s=5. This and every other link brings up an Internet Explorer cannot display the webpage.
