Error code:POL-1299 Please Help

I am getting the following error:

"Error code:POL-1299
This page cannot be displayed by PlayOnline Viewer. Your proxy server or provider may be trying to forcibly display some sort of notification. Please check your proxy settings or provider documentation."

Any ideas? The computer I am on is on a work network, but we are not forbidden from having games on our comps. Worked fine late last Friday and now I am having trouble logging in with no changes reported to security settings.

Any help would be appreciated! Thanks!

Maybe the systems administrator at your work has changed some stuff...

You will also need to follow SE's protocol when posting on the tech support forum as they cant even begin to work from what you have posted due to no information.
