ok this is making me mad...

I did a search, both specific and really general and I found the file I was looking for and when I went to download, it stopped and said waiting for busy host. I did that for two hosts and I cannot find the file on another host at all. How do I keep the computer from waiting from busy host? How do I get the file without downloading it for a long time bcause it's just a pain and it won't stop waiting.
