Vuze suddenly stopped working - certification path error

[Glassman]

I've been using Vuze for years without any issues and then suddenly today it's stopped working for me.

I can search and identify torrents but when I go to download I get error message: Error : I/O Exception while initializing download of 'http://104.20.56.43/download/4971907/':javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested targetCan anyone help me work out what's going on and tell me what I need to do to fix it?

Thx
