I think that may be it. The security is set to not allow other sites to "Hot Link" to these files UNLESS your on the COB or RacerX forum. So you might add a "RIGHT CLICK - SAVE AS" notation at the beginning thread.
Hey Mitch. The links work as long as you "right click save as" It may be a security thing. The site is set to only allow COB and Racerx sites to DL.
Are you getting into the ftp host ok?
