Access to blocked sites/downloads

First post... and since Norton support is limited to buying their products & services I'm wondering if someone can help me! Have a flash player update that security blocked, tried to link to a download for site I've used in past  and was blocked and then got blocked trying to access ESPN 3 last night! Message is "your current security settings do not allow this download". Checked my firewall settings and they (of course) are controlled by Norton 360.

Never had these problems before... been using Norton about 18 mo's. Any suggestions appreciated!
