If you attempt to connect to a sling box and it times out (Slingbox not powered on, etc.), part of the resulting message says "Click here for more information", with "here" as a link. The link is to http://support.slingbox.com/get/KB-5000340.html which gives a "Page Not Found". Please fix this.
I have to admit to being somewhat frustrated in trying to report this. It seems the only two ways are to post it here (a community forum doesn't seem appropriate), or phone support, which says it will charge me $$ just to report the error.
