Wow, that's a first... I can't imagine them being a *scam* since they provide alot of the information here on the DotNetNuke site - but what I think could have happened is mail to you might have been blocked or gone astray - it does from time to time.
Normally when you purchase items like this you get instant access to the files and you can see them when logged in.
I'd be using their contact form. I purchased a product from them about a month ago without any problems at all.
By the way - yesterday - in Australia, which is where their site is, and my site too, I had an outage for about 20 mins, which was in fact a network error. If you typed in my site it brought up google search. There was a network problem which affected alot of sites.
I've just visited the site and it came up straight away.
You know, I really think your email must have gone astray - why don't you log in and see if the files are there to download for you. DotNetNuke does this type of work automatically - the downloads should be there.
