As I said in my other reply, that was an issue related to a faulty update. And since v5.6.1 fixes compatibility with a Windows update which you're probably going to get soon, I suggest to update to v5.6.1.
I just uninstalled 5.6.0 then installed 5.6.1 and it works.

Thanks for your hard work, it helps me a lot :-)
