Not able to download SDK with AIR 15beta

Hi,

I'm trying to download the latest SDK with AIR 15 beta but it always fails
on the download of the Flash SDK. Yesterday I had no problem on another PC

My log:
Version 3.1.0 (windows)
Using Locale: nl_BE
Fetched the SDK download mirror URL from the CGI.
AIR version 15.0b
Flash Player version 15.0b

Anyone know what the problem could be?
