when i click to downloadthe Adhd-200 database，it'displays‘ page not found’.

I'm sorry, I missed your addition of the screenshots earlier.

I'm afraid I can't reproduce what you see, and I don't see anything in our logs that helps direct me.  What did your address bar say in the third image (what exactly was not found)?  If you need to run this again, you can select just a subject or two from the list at the left (in the second screenshot) to get it to return more quickly.

Alternatively, you can download the data directly from http://fcon_1000.projects.nitrc.org/indi...

please look at the pictures i uploaded，when i downloaded the ADHD-200 ，i clicked the download the images（the picture 1），then i clicked the submit（the picture 2），finally it said page not found，just like the picture3.

Can you be more specific about what you're doing when you get this error?  What page do you start on, and what do you click?
