which web browser are you using? the simplest way to check if the problem is with the website or with your web browser is to use a different web browser than the one you are currently trying to use. download and try opera, or chrome, or firefox, or seamonkey, or safari. if DN works with one of these other browsers, then there is a setting in your default browser that is causing the error. sites like DN rely on scripts to run everything, it might be php or ruby or javascript or some ajax mashup or any number of other scripting languages... your browser needs to run scripts, and all new browsers allow you to turn off scripts, whether accidentally or on purpose... so just try a different browser and see if DN works...
if there is still no joy, then it might be your firewall/antivirus/internet security program that is blocking the scripts. they tend to be over zealous in protecting and could just be blocking stuff they deem harmful even though you know it is harmless.
i'm on a mac and i let everything run freely, and DN works fine for me... so not sure what else to add... except just try a different browser... a 2nd opinion is always good to get.
good luck with it.
harmless
