"File archive" missing for RH8 Download

I want to download the RH8 Trial version.  Once I got the Akamai download manager installed, I thought I was ready.  But... it hangs saying that the RH8 archive file part is missing.  Where/ How do I get this?  I tried copying the downloader into my project file location, but it didn't find what it needed there, either.  Thx.
