I can not export HML data

Hello, I can not export XML-data because the button is grey. The buttons beneath (for export mapnik or osmarender) are all in black. What do I have to do?

Hi, Normally if the XML export button is grey, the selected area is too large. It should be enabled if you can select a smaller area. If you need a larger area, try one of the targeted region extracts from

or

Thanks for your answer! Yes, I need a larger region. For my next holidays I need parts of California, Nevada, Utah and Arizona - and all these countries are not offered on the websites you suggested, I am afraid.

Where do I find these maps? I already tried to download XAPI but there I always get an error on the website.

They are: http://downloads.cloudmade.com/north_america/united_states#downloads_breadcrumbs
