problem downloading Netherlands map

I tried to download the Netherlands map
when i enter my email adres i go back one page

OS :
Linux Mint Debian 32bit, browser Firefox 5.0
Debian stable 64bit, browser Iceweasel 5.0

Just tried the same (Ubuntu 64bit, Firefox) and experience no problems… other then that one of the servers is currently down (which doesn’t affect the website besides a slowdown during loading).
