Hi all, I'm trying to install Novell Moonlight plugin 3.0 preview 6 <http://www.go-mono.com/moonlight/prerelease.aspx>. But I got this message: «GNU IceCat could not install the file at http://www.go-mono.com/moonlight/downloads/2.99.0.6/novell-moonlight-2.99.0.6-x86_64.xpi because: Signing could not be verified. -260» I didn't get any error with the previous version (http://www.go-mono.com/moonlight/downloads/2.99.0.3/novell-moonlight-2.99.0.3-x86_64.xpi). What did happen?
