Some users have had issues here and there when upgrading the PortableApps.com Platform. Most recently when the platform switched to https-only connections before we added in the ability to fall back to http on some machines. If you've come across an issue, you can manually upgrade the PortableApps.com Platform which should fix most of your issues. Our apologies for the folks affected. And if you're still having issues after doing a manual upgrade, please let us know by posting in the PortableApps.com Platform support forum.
