Can't download the basic model (San Francisco)

[buahaha]

I have no idea what I'm doing wrong. I downloaded InfraWorks2014 today, student version and I've been trying so hard and so many times to download the model of San Francisco City and all I get is an occured error saying "some other user has blocked your downloading, try again" (more or less). Or the downloading begins but it's 0% all the time and then the program stops working. What should I do about it? I can't even use the program without any models... Is there any other way to download them? Thank you from the mountain for every little help!

Does the download get far enough to create a folder like C:\Users\USERNAME\Documents\Autodesk InfraWorks Models\San Francisco City.files? Is this happening at school, where you could be behind a proxy, or at home?  What do you see in the log (under Help)?

[buahaha]

Well, the folder you've mentioned exists but it's empty. I work at home, nothing should disturb me. Other programs from Autodesk work properly, I've got enough space on C and D so I have no idea what's wrong...
Maybe the best thing would be uninstalling InfraWorks and try again but everything was ok with the installation...
And what's under Help section:

this download can take a while its like a 2gig file

if your internet download is slow it will take a while to download

[buahaha]

My internet is not really slow but the program didn't let me download it before - every time I was leaving the downloading box opened for over than an hour to let it work but it kept on doing nothing...
But here's something new - I've finally downloaded it but now the program doesn't see my downloaded model and cannot open the .sqlite file - there's an error every time I try to open it. Everything is ok with the downloaded files, they exist, I can see everyhing in the folder called "San Francisco City.files". Does anyone have a clue?

Strange - what's the error, and what's the size of the .sqlite and the size of the associated .files folder?  I'll redownload now to see what I get.

I also can't download this file, when downloading, it always stay 0%,I think it's not the speed of the internet, how to deal with it...
