CHROME FIX: Like many others, it suddenly stopped working one day. Just a white screen on startup, sometimes with a PNC logo. Clearing cache, storage, reinstalling, and rebooting did not fix ... But for whatever reason, *setting Chrome as your default browser does fix it*, at least for me. It worked for a while even with another browser as my default before it broke, so I'm clueless as to why I needed to make the change. I hate Chrome - this isn't a good solution, but at least I have access.
