I'm sorry to hear that you're having trouble with Netflix loading. I've taken a look at your account and ran some checks on your equipment and there doesn't seem to be any issues.
How are you trying to load it? You can access Netflix by either going to channel 204 and pressing the red button or by going to Home, Apps & Games, All Apps and then Netflix. If it still doesn't load for you i'd recommend rebooting your Hub, wait for that to come back online and then try rebooting your box.
I've taken another look into your account today and can see an issue with some of the power levels that may be causing this.
To get this resolved i'd like to arrange an engineer appointment to take a closer look at this for you. I've sent you a private message so that we can arrange this, you can find this by clicking on the envelope at the top right of your page.
