Ge0rge,
If I'm reading this right I think your getting a little confused between your search results and downloading.
When you search for something the little box at the top of the search window that turns green is showing how far along your search is. When it is completely green then it is done searching. You haven't downloaded anything yet. To download the file you want you have to either right click on it then click "download" or hi-lite it then click the "download" button.
If the file won't download then you might need to reset the "License Warning" pop-up, and as Sphinx said the direction are in the stickys
. But here's the link,
license problem. Read through the different posts cause it has directions for Mac and Windows.
