I tried to download the Netherlands map http://garmin.openstreetmap.nl
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).
