Downloading Problem

I've tried downloading esf from the fileflush, and File planet, and the file gets anywhere from 1 to 10 megs complete and says its done, then after i try running it it gives a message " C:/Sierra/half-life/esf20.exe is not a vaild win32 application.

I've tried d/ling it to my documents, my cstrike folder and half-life folder. and can't figure out what this message means. I use Windows XP is that helps determine the prob.

if anyone could help i'd really appricate it.

Try downloading GetRight or GoZilla! they can restart a dead DL which is your problem.
