Well, I got to "Properties", clicked that, and for type of file, it just says "file". Also at the bottom of the box a warning that this might come from another computer posing a danger. From what's been said about it being a possible pirate site, and the fact that my emails are returned undelivered, I think I'll have to write off the £8-37 ($9.99), and put it down to experience.
Many thanks, anyway for all your help and time.
Cheers, Howard
