Windows 8.1 has just completed a major update (not sure why).

I have internet access, and some programs (Google Earth etc) are able to access their update server.

However, with email (Bluebird - firefox), CCEnhance, and Belarc Advisor ( as examples) I am unable to get connection to their online update server.

Have run through multiple diagnostics, system verified, and verified netframework to no avail.

Ideas pleas.
