I've got D2 on my Battle.net account. I am trying to download it. It will not let me. Every time I run the downloader, it gives me the error that my download is not authorized. I have been Googling the christ out of this issue and nothing has worked. I am on Windows 7.

I tried Run as Administrator.
I tried checking "Run as Administrator" on the compatibility tab.
I tried creating new folders, downloading to both Program Files folders, and the Public\Games folder.

It will not let me download. Can anyone help me? This is piss.

you need to do the download process all over again you cannot pause it then come back to it as it expires after a certain amount of time....
if your trying to download it go the site and click download dont click the downloader thats on your pc coz like i said it expires.. try it worked for me
