if a good link you klick takes you to a different site then it's safe to say there is spyware / adware on your computer messing with your browser, taking you to adfarm websites instead of your actuall destination. If you don't know how to fix this then i would try a different computer to download it.
Look in the pokemon b/w translation thread on the first page of the rom hacking forum (the one with 180 pages), the link is on the first post, and i checked to make sure it works.
also, you are talking about Rudolphs Childsplay for Black/White? Because that's the only patch i know of.
good luck, let me know if you run into any more trouble.
