Thanks for the program johnyboy. I found out it was my set up which was causing the downld problem. I was using Speed Download. It was misreading the MIME of the filetype or something like that. But using browser by itself worked fine. Also Stief was able to downld it without problem. Thanks again. I think there'll be a no. of people who will find it useful.
Windows users often have this problem with corrupt downld preferences for various reasons such as system crashed. But they'll have to find their own.

I'll give you some feedback as soon as I've tried it out. I'm running Tiger.
