I've followed the wiki page on how to adding the keys using ed2k.reg file to associate ed2k links to aMule in Windows but can't seem to get it to work. I'm on Windows Vista SP2 and using Firefox. When I click on a ed2k link I get a Launch Application box with "C:\Program Files\aMule\ed2k "%1" as a selection but when I select it and click OK it doesn't do anything. Am I being really stupid and missing an obvious step?
